miscarriage and TTC

Amy
So after a little over a year of trying, and waiting to get my boyfriends sperm tested (as I have a soon to be 9yr old from previous relationship) I found out I was preggo. I got two hcg tests done and had all the symptoms. I'm an er nurse so I wanted to make sure the beta hcg doubled and it did. We booked a 12 week u/s so we could do something cute to announce to extended family(our parents knew) and there was no heart beat. 
It lead to cytotec two doses and not working and a d&c.
I haven't had a period yet took the test and am ovulating but I am so disheartened. 
And as much as I know the stats it's so hard and I'm back to tracking periods, ovulation and taking maca
