CD 50 and nothing 😥 I need advice

Trisha
My husband and I have been trying to conceive for a year this month. I have had a history of irregular periods. In May 2015 I took a progesterone to regulate. I was regular through November 2015, then I missed a period until February 2016. I took a progesterone again in April. I was regular April and May now I'm nothing. I'm wondering what i need to do now. My obgyn doesn't handle infertility. Idk what my next step is. Please help!
