I was told at my prenatal class that it is completely normal to bleed after intercourse and after a check down there by the doc. We were told and the nurse repeated not to worry about this bleeding when it happens. Hope this helps a little.
YES IAM 2CM OPEN LAST TIME THEY CHECK ME OUT THAT WAS LAST WEEK AND THE BABYS HEAD WAS -3
A lot of times when you bleed after intercourse it can be caused by an irritated cervix... I would definitely bring the issue up at your next dr's appointment just to make sure that you are not dilated and are at risk for preterm labor =)
