Hey
I had unprotected sex on Thursday. My boyfriend says he did not ejaculate inside. But I am having periods like pain and a FULL feeling in uterus. I took emergency contraceptive (levonorgestrel) after 12 hours of intercourse. What are the chances that I may be pregnant. And how to avoid it? What is this pain about?

How to avoid pregnancy? The only guarantee is to not have sex. There is no other guarantee.

Are you saying you had 12 hours of sex and then took an emergency contraceptive OR you took it 12 hours after intercourse?

Your boyfriend does not have to ejaculate inside you for you to get pregnant. I have no idea why you have pain or a "full" feeling. You would not have a "full" feeling two days after getting pregnant (if that is what you are asking).

You need to understand how your body works before you continue to engage in sexual activity. Here's a start: Female Body - Ovulate - When Do You Ovulate - Menstruation Cycle

Noooo... took it 12 hours after intercourse :S
I am just asking the reason of pain I am having after since I had sex.. is it normal or something related to pregnancy?

The discomfort may be partly due to the recent sex, but also likely due to the emergency contraceptive which carries a much higher level of hormones than regular birth control pills.

As JudyKayTee said, you wouldn't be feeling any of those discomforts due to pregnancy at this point. However, pregnancy is still a slight possibility even after taking the levonorgestrel, so see what happens when you expect your next period.

DoulaLC... thanx a lot for your answer..
