My first pregnancy i bleed for the first 4 months sorta like a period but after 4 months it stopped and i had a healthy boy 8 lbs 8 oz and not a problem though my pregnancy. so don't worry until you see the doctor becasue the bleeding could be many things i know it is hard not to worry but try your best.
I haven't had your exact experience, but I do know bleeding is caused by all sorts of different things, and not all lead to miscarriage. I hope your ultrasound shows a healthy little bean, and that you have a healthy remainder of your pregnancy.
I am 7w4d and I also has spotting like that a few weeks ago which last 2 weeks.....my spotting stopped a week ago. I had an u/s done last week and saw a very healthy heartbeat.
I had severe bleeding the first three month on my pregnancy. I'm now 30 weeks pregnant. Bledding in the first trimester can be normal.
