Provera and TTC

Tori • 28. Benjamin born 4/17/19. IVF warrior.

So I'm just curious. I have been TTC for the last 9 months, but I didn't have a period for 10 months (last one was aug 2014). My doctor prescribed me provera to jump start my period. Boy did it work! I had the period from hell last month. My question is, is it safe to still be trying while on this medicine? The doctor said that once I'm regulated to come back in and then we can revisit trying to get pregnant. That worries me because I don't want to harm my baby after trying for a while to get pregnant.

If it matters, I'm 21, overweight (270ish), and work in a very physically demanding job.
