Help!!!

I had a miscarriage 11 months ago. Me and my husband are trying to convince but we have had a hard time getting pregnant. I'm starting to think that I can't get pregnant again. But I've gone to the doctor and they said I'm fine. My husband wants a baby so bad. And every time he brings it up it hurts me so bad. 
​ Is there anything I can take at home to help boost my fertility and conceive faster??
