TTC this month and the last 3 days I've been feeling some symptoms , however I'm still in my ovulation week . But the last 2-3 days I've been feeling very slightly  nauseas , not hungry , last night I had lower abdomin/pelvic pain during sex and cramps for a few hours after , today the nausea is on and off and I thought for 2 seconds I would throw up , my sense of smell is really heightened last night and today which isn't normal I don't have a good sense of smell , and urinating more frequently even if it's a little , etc . Yesterday though was my first positive with OPK so I don't know what to think . There's 3-10% chance of pregnancy before ovulation and during ovulation It get get up to 37% .
