I've been having bleeding issues lately, too... nothing severe, but I called my hcp just to let them know and just to get some reassurance... Her main concerns were that I wasn't having any contractions to go along with the bleeding... and she also said that if the blood was just there when I wiped versus bleeding out onto my underwear or whatnot, that I was fine, too..
So, just check in w/your hcp to be sure... but it sounds like things are just fine!
