I need help. Its my 3rd round clomid.,. Please answer

I am on cd 32 . I still have negative hpt's. Spotted light light egg white consistency yesterday morning (had sex the night before) and now no blood at all. I had a positive opk on cd 14 ( 7 days after last clomid pill) and BD every day. I was curious if any of you ladies were pregnant even after negative hpts and no AF. Please tell me your experience with clomid. Im also on metformin for pcos.
