Thanks ladies. It was only a light bleed mwaris and stopped that day, but I thought 9dpt was a long time to be attributed to implantation bleeding but maybe I'm a late implanter!
I think I have to take 5mg prednisolone until the 1st scan, which PFC have asked me to do in 2 weeks linbruzaite. I haven't heard of the link to birth defects. I believe it helps to stop your body rejecting a "foreign object".
