Hi Suzie,

I too have (or had) a Sub chorionic hemorrhage with this pregnancy. It is my understanding that it is a bleed between the uterine wall and the placenta. Most of the time they get reabsorbed into your body without any worries to you or the baby. Worst case scenario is that you can get excessive bleeding resulting in MC, or premature birth (which are both WORST case and usually starts with bleeding from the very beginning)
Mine looks to have been reabsorbed into my body. I did have a bit of spot bleeding a few weeks ago after sex, but it disappeared in an hour. I have been trying to take it fairly easy and not do any excessive lifting, though I do still pick up my 25 month old son I have had no real problems. I would just take it easy until your next scan where they will do another check on it.
Hope this helps... Wishing you all the best for the remainder of your pregnancy
