2 periods in one month

Ever since October, I have had 2 periods in one month, and I’m not sure what to do. I have been to 2 doctors and neither one has told me what’s wrong. They only try to push me to get the IUD to stop the bleeding. I have been completely off birth control since May 2018, and have been trying to conceive since, but it hasn’t worked.

My question is, does anybody know what could be wrong? And does anybody know if it is even possible to conceive with a period like this?

I am ovulating right now, and we’re trying this month, as we normally would, but my period is due in 3 days, based on when it normally is. Is it even possible?
