Hi Renee,
First of all, welcome to BB and I am so sorry for your losses . You've had a really rough time hun! I can't personally say that I have been through what you have been through, but my advice would be to maybe visit your doctor who then can refer you to a F/S, if you are trying to conceive and have not had much luck in the last 12 months. I'm not sure how old you are, but if you're over 35 they say if you haven't conceived in 6 months of actively trying, go and see a F/S. You might want to check out the TTC after a miscarriage thread, maybe some girls would be able to help you there ?
Good luck hun, I hope you find some answers soon.
Beata
