Pregnancy and period issues

My partner and I are trying to conceive. I’m 32 years old and have not had a period since May. All pregnancy tests have come back negative. My periods have been irregular for a while now but I haven’t missed a period for 2 months. I’ve spoken to my OBGYN about starting birth control to kick start my period. I know I need to also lose weight but I’m concerned about being able to conceive from missing my period for as long as I have. I’m feeling broken. Any stories of pregnancy and birthing a baby after having inconsistent periods would be helpful. Tips?
