FTM momma here & I haven't bled after sex my throughout my whole pregnancy until now.. It was a tiny bit of red blood but now it's just pink with normal sex fluid lol (sorry TMI) Normally my hubby & I have a pretty decent sex life, at least a couple of times a week we have sex. But since I was sick for a week & then the next week he had been in the hospital & had surgery so we haven't had any at all until now (it's been like 2 & a half weeks) could that be why I bled?? Because there hasn't been any action down there?? Someone reassure me! Lol I don't wanna make the trip to the hospital & I called the nurses line & they said to call back if it worsens but I need someone who's experienced it!!
