Do get it checked out-- it's possible to bleed quite a bit without a miscarriage, so even though you may well be right, do see your doctor. Okay?
I had severe early onset pree (resulting in the death of our daughter), followed by what were eventually 5 miscarriages. Please feel free to message me privately, if I can help. In my case, although they strongly suspect autoimmune disease that isn't yet detectable, they were never able to find an underlying cause. We're now pursuing adoption.
I've met many women who seem to have both pree and miscarriages, and I don't know if this makes you feel better, but I seem to be one of the very unlucky few who can't seem to get past 10 weeks after the preeclamptic pregnancy. Most do find their way through.
I'm happy to answer any questions I can about the kinds of tests they did, and what I found from the research.
I'm sorry for everything, and I hope you get resolution quickly.
