9 weeks and bleeding

Je

I am 9 weeks today. I have been spotting brown for 2 days and now today I am full on bleeding red and a decent amount. Not filling a pad but enough to cause worry. I don't have cramps just a little achy feeling in my abdomen. I had a private scan Saturday and heard a healthy heartbeat. Please pray my baby is okay. I go for a scan today at 230 and am a worried mess!
