I am 27, married since one year and is trying to get pregnant. I have a 35 day menstrual cycle and had my last period on May 11th. I have never used any birth controls (my husband was using condoms) We had regular intercourse once daily, from 25th May onwards and on June 2nd while he was penetrating inside, I had a severe pain deep inside the vagina and while I was cleaning the semen later, I noticed a pink color in the tissue paper. This was around 11 o clock at night and after that I slept. Again I got up at 2 o clock with severe abdominal pain and bleeding. The pain was very severe for the next 4 hours and started decreasing after wards. I went for the gynecologist and I couldn’t let her check me with inserting that speculum down there, because it was hurting me so much. So she just asked me to take rest and so I did. She did the blood HCG test and it came out negative on June 3rdThe bleeding lasted for 2 days and now I am free of the stomach pain and bleeding.. Now I am worried why it happened like this and whether it is a miscarriage or something, because I never had any bleeding like this (in between the cycle and after intercourse) before in my life. Or if there is some problem. Can this happen again?
