is everything okay??

i miscarried back on October 16th 2018, didnt received my period back until December 2018 i had my period in January and February but havent had one since, nor am i sexually active at the moment. is it normal to experience gaps of no period after a miscarriage? this will be the 4th month with no period. should i be worried? i feel like my body had the time it needed to heal, and i should be getting a cycle.
