Help! Advice plz!

Okay so I went off of birth control November 2017 and I got pregnant in feb 2018 and lost it in March. I then was having my periods regular every month but then I stopped having them in August and September. Well my doc gave me medicine to try an have a period and a baby and my husband isn’t wanting to do that right now because he says medicine isn’t the solve for everything and I just don’t know what to do 😭 idk why my periods are off like this.
