I had bleeding in the first tri around the 9 week mark which was very worrying.I had an u/s that confirmed that bubs was okay.On the u/s they could see where the bleeding was occuring but no explaination for why.I bled for about a week and it just got lighter and went away.
I had a baby girl in sept! Ruby grace.She was on the small size as i had a case of placental deficiency,whether this had anything to do with the bleeding i dont know? But she is a little pudding now! Hope that it stops soon for you and that you can enjoy your pregnancy.Perhaps check the thread on bleeding in pregnancy for others input too?
