TTC with PCOS

Rosa
Hello everyone, I've been going crazy for the past week and thought maybe someone had a similar story. I've been trying to conceive for about 5 years with my husband I got diagnosed with PCOS in 2013 and just started seeing an endocrinologist in February. He prescribed me metformin 1000 mg and 3 days after I started having a period but now I'm just kind of stuck waiting for a period my app says it's due and it hasn't came I've took tests and they're all BFN's :(
