Cycle lengths and fertility

So i had an mc last 4th of july and before then my cycles were 28 days with 5 days for my period but ever since my mc my cycles went anywhere from 30 days to 36 days and sometimes my period would only last like 2 days. This has been the first month that ive had a 28 day cycle since my mc so does this mean my body has finally gotten back to normal? And if so, does this increase my chances to get pregnant again? I have been trying ever since my mc with absolutely no luck...maybe im just having wishful thinking...opinions would be appreciated! Has anyone else gone through this after an mc?
