I was on the day I was due to bleed and I felt a little hyper like I usually do so I had sex and I passed a table spoon ish of menstrual blood. Then over the next three days I passed about a teaspoon to then half a teaspoon of blood and did a pregnancy test twice and found I was definitely pregnant. For the next few days I had all the symptoms of pregnancy and the blood stopped by the sixth day after the day I was due to bleed. I was feeling emotional at this stage and so on the seventh day had very gentle intercourse. The next day I miscarried. If I had not had sex would I have still miscarried? My skin in general is sensitive and I had had a slight soreness, burning sensation of my cervix since I had conceived. Was my cervix depleted and then worn away in someway from sex? I phoned my GP and he did not know.
