I had intercourse for the first time last week, and then again for the second time the next day.two days in a row. The first was last Monday, and the second was exactly a week ago. I got the injection a fortnight ago and My partner used latex condoms. The first night, the condom burst, and we decided to stop as it was hurting me too much. I noticed a slight cramp in my abdomen area shortly after but it wasn't painful enough for me to properly take notice. The next day. again we never got to finish as it was too painful for me. Afterwards I noticed I had the same cramp as I had the day before, but only worse. I put this down to being constipated. But it has been a week, and my bowls have moved yet it still hurts. in fact not only am i getting occasional cramps but I am getting an occasional sickness feeling too!! What is going on?
