Ttc after mc

I had a mc on 2/18/16 at 9 wks and have been ttc since but am not having luck. Every negative test result is like a jab to my stomach and it doesn't help seeing fb posts about pregnancies and babies. I'm frustrated, hurt and angry. My cycle isn't the same as it was before my pregnancy and I don't know if I should just see a specialist or go back to my doctor. Was it difficult for anyone else to conceive after mc?
