Has anyone experienced a delayed 2nd period after taking Plan B One-Step?

Hi. I just wanted to share my situation and see if there were other women out there who may be going through the same thing.

I took Plan B One-Step about six weeks ago after an unprotected incident. I say incident because it was just really brief unprotected penetration that lasted <30 seconds. I panicked as my period tracker indicated that I was in my "fertile window" and due to ovulate soon. I purchased the pill and took it the following morning about 17/18 hours later. I was hesitant to take it, given its many side effects, but had worked myself up to go through with it just in case. I was fine after taking it, no symptoms. I was an absolute emotional MESS though. My anxiety was out of control and I ended up losing about 13 lbs throughout the experience. I was depressed and constantly upset. And this was from a situation that was already unlikely to cause pregnancy to begin with.

Anyway, I started experiencing some PMS type symptoms just over a week after ingesting the pill--slight cramps and hot flashes. The cramps were strange for me. They were concentrated in my pelvic region and felt like my pelvis was on fire. Normally I have just back cramps. My period ended up starting on June 7--two days earlier than I was anticipating--and was a totally normal period. I experienced heavier clotting than normal, but it was otherwise a completely regular period for me. Lasted 5 days, started out light and got progressively heavier, then ended lightly. Mind you, I was experiencing SEVERE anxiety during this time. There was one day I had to call in to work because I couldn't even get out of bed from depression. It took another week after my period had ended for the anxiety to calm down. I went on with the rest of my month as usual. Perfectly happy that I had gotten through that experience and ready to move on with life and make better choices about my health and sex life.

My boyfriend and I have not had sex since this incident, which occurred on Memorial Day 2015. Therefore, it has been six weeks since this all went down. My period tracker said I was due to start back on my period again July 4--estimating a normal 28 day cycle, which is typically normal for me. However, here I am on day 33 after my post Plan B period and I have no sign of it. No PMS, no spotting, nothing. I have two negative pregnancy tests that were taken on days 30 and 31 using First Response. At this point, I'd be considered 8 weeks pregnant and that should show up on a urine test. I have no symptoms of pregnancy either aside from a missed 2nd period. I'm really frustrated. That time was really dark for me and the amount of anxiety I experienced was so beyond unhealthy. I am really trying not to worry myself too much at this point, as it is still highly unlikely that I am pregnant. Last night I began experiencing sore breasts. Nothing too insane, but just slightly tender and heavier feeling. I noticed my cervical fluids were thick and white/cloudy in color. I think that is normal, as I have noticed it before. I just want to know if anyone else has had an experience similar to this one. Normal period after Plan B One-Step and the next one was late to the party or a no-show?

Just posting this since I went to forums like this when I was in this situation! Took the morning after pill twice in one month; took the first pill and got the “fake” period a couple days later then took another pill a few days after that and also got the fake period again. My period was late, took 3 pregnancy tests (one every week) all negative. Period finally came and was about 30 days late so I basically missed one whole period! Morning after pills really do f up your menstrual cycle, so don’t worry if your period doesn’t come. I would take a pregnancy test just in case though and if that comes up negative then it is most likely right you will just have to wait for your period to come!

Hi everyone,

Just wanting to share my experience with Plan B, since this is where I came when I was freaking out. After taking plan b, I experienced spotting before my period. My period came on time and was normal. Here's where I really freaked out-my second period was the WORST. I never get any PMS symptoms but this time around I had really bad cramps one day (about a week before my period), back cramps, and I became so anxious and paranoid. My second period came 5 days late. Before the second period my ovaries felt weird, not painful, just similar to how they feel before ovulation. I have never felt so anxious and paranoid so I wanted to share how I felt before/after my second period since there wasn't much on here about it. Good luck!

I want to share my experience for any women who might be going through this -

I've taken Plan B in the past and haven't reacted this way before so I too was a little concerned. When I took plan b back in September, I had my period a few days later. This cycle came on time, but was a lot lighter and shorter than expected. I was fine with that since I knew it was because of plan b. Then... my breasts started hurting and were sore for about a week and my emotions were out of control. Never had that bad of depression/anxiety before. These symptoms didn't come until a few days/after a week later. Took a pregnancy test just to be on the safe side and for my own sanity. Everything was good and came back negative.

Around comes time for my second cycle and this time it was OVER A WEEK AND A HALF LATE. I was freaking out naturally of course. I did not take a pregnancy and was just hoping it was because of plan b and whatever I read online. Either way, it eventually came and I was overly relieved and joyous. My cramps right now are awful, however, and I'm just waiting for the pain to end. BUT KEEP THE HOPE ALIVE AND DON'T STRESS TOO MUCH!!!

I just went through a very similar experience. I used plan b as a precaution after an incident almost identical to yours. Better safe than sorry. I experienced some symptoms about 4 days after taking it, but by day 10 I had gotten my period, although it was a week early. Very normal period.

I too was ready to put this awful incident behind me, so I was very nervous when my second cycle was late. I understand that stress can causes delayed ovulation etc.... And I think this is what happened to me. I was supposed to ovulate around July 8, and then I noticed more fertile cervical mucus on the 12. So I did my best not to freak out (read: only took 6 pregnancy tests, lol) and waited. I also would've been 8 weeks, so I knew the test should be accurate. I got negative results. If I count from the first day of my "first" period after plan b, I did not get my 2nd period until 37 days later. Try your best not to freak out, your chances of pregnancy are slim, but I know it's still upsetting. It's very normal to have a long second cycle after taking plan b.

How was your third period after that? I got mine on day 36 for the second period and now approaching my third. Not sure if it will come in a normal time frame or if it will also be a little late. I know it is going to throw me off as I had intercourse once since then. But it was protected this time. No ejacualtion either. I hate that stupid pill.

Hi Anon,

Thank you for sharing your question with the EmpowHER community.

Some women do experience side effects after taking Plan B One-Step. Menstrual changes top the list of side effects. The menstrual cycle can be delayed or even come early. The flow can be heavier or lighter, or there can be spotting.

I hope this information helps and that some of the other members of the community chime in with their personal experiences.

Be well,
