This morning I went to the bathroom and when I wiped myself and there was light blood. I wasn't bleeding it was only when I wiped. So I went to the hospital and when I gave a urine sample there was no blood, not even when I wiped. It was just that one time this morning. This is the first time it has happened I'm 22+6 weeks pg. The baby is fine. I'm just curious has this ever happened to anyone? What could it have been?
