My LMP was Dec 9th and on Dec 12th (saturday)I had unprotected sex and took plan B. I took one pill that evening and I took the second pill late, i took it 15 hours later insetead of 12. In fear that the pill did not work I took another dose on Monday. I started to bleed exactly one week after taking the first pill on saturday Dec 19th, I've read that the bleeding could be "withdrawl" bleeding. Is it possible to ovulate again after having the withdrawl period?
My period is now late. I took 3 pregnancy tests this week and they all come back negative. Could it be that I will NOT get my period this month because I took 2 plan b pills in 3 days. I will also mention that I've been stressed out since having unprotected sex but I don't think i can relax until i get my period. Pleae help!!

Hello Anonymous,

The best thing to do is take a home pregnancy test. Two months without a period cannot be blamed on Plan B alone.

I had unprotected sex in september, took Plan B and got my period the next week. I did not have my period in October and took plan B again on November 3rd and haven't gotten my period yet. What are the chances that I am pregnant? Starting to freak out.... Going on the pill again immediately.

Hello Anonymous,

You need to be seen by a gynecologist or your primary care physician.
You have not had a period since September and have taken Plan B twice. A blood pregnancy test and blood tests to check your hormone levels might be necessary.

Hello Anonymous,

If you have not had vaginal bleeding by now, you should take a home pregnancy test.

Hi, I have a question. If I take plan b a week before I'm supposed to get my period will I get two periods in a month?

Hello Anonymous,

Thank you for your question. No, you probably will not get two periods within one month. By taking Plan B the week before your period is due can cause your period to actually start earlier or later.

Me and my boyfriend rubbed together for a minute but he didn't cum nor did we have sex. I took plan b the next day. And the day before my period had just ended. I haven't had any symptoms except for stressing ALOT which makes a nervous feeling in my stomach and September 16 was my last time I got my period it's now October 22 no period .. Could plan b make me a week late? I don't normally count the days but sometimes I'm late because I am an athlete.

Hello Anonymous,

Thank you for your question. Taking Plan B on the day following the end of your period is most likely the reason your period is late. Stress and being an athlete are also contributing factors.

Try to relax, and I am sure your period will start soon. From what you described, there was never a risk for pregnancy.

Hi so I need some help. On July 19th I had unprotected sex and the day after I took the plan b pill just to be safe, I still wasn't getting my period so I took a pregnancy test and it came out negative. Then about a week later on July 31, my period came. It was a lot lighter than usual and lasted about 4-5 days when usually my period lasts a full week. Then a night before I got my next period, I had unprotected sex but not even for that long and I got my period the next day. And again the period was really light and lasted 4-5 days. As of today I still haven't gotten another period. I've taken 3 pregnancy tests and they were all negative. I don't know what this means and I don't know what to do. I'm only 16!!! Please help me.
