Ok so I'm on cycle day 37. I have irregular cycles... Longest I have ever gone is 35 days... I am super nauseous at night and some during the day, my breast are super tender, and my stomach cramps feel so different than I have ever felt.. Almost feels like my stomach is stretching pains.. No sign of my AF at all.. Took a test this afternoon and got a BFN.. Any advice? Obviously there is a chance I'm not preg but I really feel I am.. Maybe I'm testing too early??
