Miscarriage/Blighted Ovum

I found out on Oct 11 my HCG wasn’t rising appropriately and the pregnancy was most likely not viable. I went in for an ultrasound on the 12 to find out it was an empty sac at “7” weeks. It stopped growing at 5.5 weeks. I went home and was put on a medication to get things going. Took it the 14th and I am still bleeding a lot. This Thursday the 28th will be 2 weeks. I have an ultrasound to see where we are at on Wednesday. This was supposed to be my third baby. It is my first miscarriage. I am hoping to try to conceive again but I feel like I’ve been bleeding forever and I’m scared I won’t get pregnant again. Has anyone had a similar situation? My Dr hasn’t been much guidance and I really don’t know what happens next once bleeding stops or when it’s supposed to or anything.
