hi. I want to find out if I may be pregnant.
I had intercourse during my period,I then took an emergency pill. two weeks after that we had unprotected sex. I have been having strange changes in my body. I've always been feeling tired, headache abd weird food cravings. I was supposed to have my periods on the 16th this month, but they didn't come. I have been feeling tired,my legs get swollen sometimes and I easily get tired, can't stand for a long time. I have been nauseous. I ahd pregnancy tests but they all came out negative. I had a pregnancy test again today, but it is negative. I always feel this pressure in my womb, very uncomfortable, I cannot put on my jeans any more because they feel so tight and the make me feel uncomfortable and tired also, I have mood swings, changing... I have too much temper and I cannot walk long distances anymore. I pee often and my appetite has also changed.. could I be pregnant? if not what could it be then? please help

A lot of pregnancy symptoms, like the urge to constantly pee, develop later in pregnancy. The only symptom that you should have right now is a missed period. You could be having an unrelated sickness and because you know you had risky sexual behaviour it is at the top of your mind.

To put it another way, you've subconsciously decided that you're pregnant and now everything you feel, normal or a little different, you're trying to use to support the idea that you're pregnant. When you're not. So you're using all the common symptoms and trying to take something that is going on in your body look like a pregnancy.

That isn't to say that you're not pregnant, you very well could be because you had sex two weeks after the start of your period which is often the fertile times, but that the symptoms you're having aren't related to pregnancy.

So what you need to do is wait until the end of the month, the 30th, and if you haven't gotten your period then take another HPT. You tested early and it is easy to get a false negative that early. As well talk to your doctor and get checked out. You might have an illness.
