Worried

Elizabeth
I got diagnosed with pcos back in February. They put on a medication called metformin. I took it for all of February and March.. I haven't had a period since the middle of March. I have taken a couple tests last month but came back negative. Starting to be more stress to take tests and be disappointed. Thinking that maybe I just can't have kids. Idk what to do. My boyfriend of almost two years is so supportive. But I'm still just worried. And advice??
