Praying, praying for that BFP!! (PCOS story)

My last period was April 2nd. Usually my periods come every 2 to 3 months so I was expecting it May 28 closer to the 2 month mark especially because I started Metformin April 27. Last Monday I happened to check my ovulation and I had a smiley face so we BD on Monday and Wednesday. I feel cramps galore but no period... I took a test two days ago but no BFP. I am holding off for another 4 days. I feel bloated and some pressure and also as soon as I drink something I need to pee. Praying I get that BFP at 11 dpo because this is annoying!!
