question !

glow predicts my O date to be monday the 28th. i don’t track with opks. i had sex the 24th and today the 27th. also planning to have sex the 29th. i feel quite nauseous. would that be due to ovulation ? i’m never nauseous inbetween cycles. every now and then random months old get ovary pain with some cramps which usually indicates i’m ovulating (i asked a doctor) but am just curious why i’d be nauseous. also , i noticed i started to have stringy ovulation discharge wednesday and thursday but now i have none at all. i’m “wet” but that’s all.
