Soooo my Glow chart just switched and said I'm 1 DPO 😱😱😱😱! Just after I logged yesterday's data, it changed. It originally said i was due to ovulate on the 15th (Saturday) & now I'm 1DPO & AF due 04/27? I've been having cramps on one side and back pain, so I'm not sure if I ovulated early or not (I only tested once 4 days ago & it was a faint line ( negative) so maybe I did ovulate earlier than expected) BUT please someone help!!!
