Can someone please tell me which day you think I ov? Ff says cd 19 but Ovia says cd 20 and a friend of mine said cd 21 from looking at my chart. I FEEL pregnant but I tested yesterday and Tuesday with frer and got negatives. With my daughter I got a positive on a frer at around 10dpo and for my mc I also was able to get a positive before a missed period as well.
