I have a cycle that ranges 33-38 days (adverage 36) so I believe I ovulated between days 18-25 ... so what I believe is 5-6dpo I had light pulling feelings on both lower sides and little tingles in breast ..I tested 10dpo BFN😔...Usually 5-6 days up til AF I have bad cramps and bloating and diarrhea (TMI) but I have HAD NOTHING I'm CD35 and still no signs PMS .. I tested 12dpo and still BFN 🤦🏽‍♀️.. my nipples look alil darker to me but it could just be pregnancy eyes going on lolbvs🤷🏽‍♀️.. Have I missed my month or do i still have a chance???
