Could someone look at my bbt chart please? I am 3 days late for AF (15dpo) which is incredibly unusual but keep getting bfns. I noticed my post ovulation temps were lower than usual for about a week. Is there a chance I didn't actually ovulate until the day I have circled? Around the ovulation date natural cycles have given I never actually got a positive ovulation test. If I did ovulate later I am probably still not pregnant because we only baby danced once 3 days before :(
