So I'm about 4 weeks pregnant I no it's early but me and my boy friend had sex and I started bleeding a little bit the next day I had brownish color blood come out and the the following day I started have red blood come out with blood clots and it's still happening but not really severe pain only like menstrual cramps. I had my blood taken twice and have a follow up with my ob. But has anyone had these things happen and not lose your baby???: -(
