Help please! Be kind..i have pcos

My period was due 5 days ago. No sign of AF. I Have PCOS, I miscarried 2xs last year. My last one was in November. I did not naturally get my period in December due to the miscarry. I got my period in January and Feb. Im also on metformin hcl 500mg 3xs a day, and i took chlomid days 3-7. I have not gotten my period im 5 days late. I have taken 7-10 hpt's and all BFN!!!! Can anyone tell me if they got their BFP after going through all this? Im every emotion in the book right now! Can anyone shed some light?
