Is it normal to miss a period after taking plan b?

Hello Anonymous,

The Plan B package instructions state that you should take one pill within 72 hours after unprotected sex and the other pill 12 hour later. The pills are more effective the sooner they are taken

It is too late to take the second pill. I cannot predict if the first pill alone was effective. If you do not get your period within 3 weeks of taking Plan B, test for pregnancy.

Hi, I forgot to take my second plan B pill, now it's been three days after I took my first pill.

Should I take the second pill now??

Am I going to get pregnant?! I'm so stress out because of this!!!! Please help!!!:(

Hello Anonymous,

Some women will experience changes in their menstrual cycle as a side effect of Plan B. Periods can start earlier or later than normal. Menstrual flow can be lighter or heavier than normal. That is what is happening to you.

Ok can someone please help me I'm literally freaking out. I had my Lmp may 31-June 3. I had unprotected sex June 8. Took plan b around 10pm on the 9 and the second dose at 10am on the 10th. I've had really light bleeding for one day then weeks past and had it again. Since then I have taken 5 pregnancy tests and they all came back negative. Today is Aug 10 and I still haven't had my period. What could be going on?

hi so i had sex on august 4 and the condom broke...so the next day i got the next choice/plan b to be safe because i sometimes son't trust the birth control and keep in mind that i am on the pill and i take my pills regularly.. the 5th was when i was suppose to be taking the green pills which causes me to have my period..i have taken 5 of the green pills and still no period and its the tenth today and im getting the cramps that you get before you get your period...does that mean i'm pregnant? PLEASE HELP

So I don't have an exact date for my period but it always comes sometime at the end of the month. I had unprotected sex about July 23rd and two days later I bled for two days a very dark blood it almost looked black with little cramping. It is now August 8th and I have no signs of getting my period. Any advice?

mmm i had unprotected sex in june took plan b and had my period that month then comes july and i totally missed it i was suppose to have it around the 25th and now were on august the 8th and still no period!! should i be worried or no?!?! i took a test on august the 5th and it said negative but i just wna double check

I had unprotected sex on July 12 (the last day of my period), he pulled out. I took Plan B 8 hours later. For the next 5 days (until July 17) I experienced mild pain and pressure in my lower abdomen. 3 days later on July 20, I started bleeding heavily which lasted for 8 days (until July 28). Since I've stopped bleeding, I'm still feeling discomfort and pressure in my pelvic area. It is now August 8, and still feeling like this. Should I worry about being pregnant? Is it worth taking a pregnancy test? If so, when should I do that? Any thoughts would be appreciated.
