I have the same problem. I went to a gastroenterologist in 2008 and he confirmed my intestines are healthy. I go to the OB once and year, and nobody has told me I have problems. It's already 2010, and the problem has started coming back. For 2 weeks, I cannot poo anymore without the help of a tablet. I tried pooing today without the need of a tablet, just one poo droplet came out then lots of blood drops coming from the vagi-gi. As I have been in a long distance relationship, I also bleed (menstruation arrives) after two days of consecutive sex. I am goin to the doctor tomorrow. I hope, though, that someone would give me an insight as regards this topic. Thanks.
