First pregnancy miscarriage

I was 5 weeks and 4 days when I lost my first pregnancy. me and my husband want to try again once we move (moving to a different state) but I have an irregular period so to get pregnant I have to go on birth control ( that’s how I got pregnant the first time was on bc for 3 months) I still haven’t passed the baby is it okay if I go on birth control to help get my period?
