I m 14 weeks pregnant, and at 3 am, for the past 3 nights I ve been bleeding. The first night was the worst, but the 2nd night was less and, at 3am this morning it was not enough to get onto underwear. I ve been to the ER and they listened to the heartbeat and the baby sounds fine. My cervic isnt open, so I did not have a miscarraige. why would i be bleeding at the same time for 3 nights in a row?
