is it me or him?

I'm starting to feel my boyfriend has a very low sperm count or something. We've been trying since august of 2016. I know he isn't sterol because we conceived in June of 2016 & miscarried on July 22, 2016. Could it be my cycle? Does your cycle have to regulate after a miscarriage? If so how long does it take?
