Doctor won't help! Any advice?

Ali

My period is 16 days late. My boobs are incredibly sore (they have been since my period was due), very swollen and hard and covered in dark blue veins. Negative pregnancy tests. Went to the Dr and they won't check what's going until I haven't had a period for 3 months. They won't even check my hcg using a blood test. I haven't had any cramps or spotting, just sore boobs, occasional nausea and headaches. Shall I keep hoping for pregnancy or just give up and wait for my period?. I'm not sure I can take my painful boobs anymore. None of my bras fit now. :( feel like I'm in limbo
