Cervix and mucus after ovulation

Does anyone else go off of their cervical mucus to know if they are pregnant or AF is coming? My ovulation test was positive on 19th but calendar says ovulation day is Wednesday20th. My cervical mucus was clear stretchy 18th-20th normally after my ovulation I go to creamy/ watery, but it’s been clear gummy stretchy 21st and today 22nd during the day but now this evening it’s just wet. My bbt has gone up yesterday and today. I’m really hoping I’m pregnant, but I don’t want to think just because mucus changed or cervix isn’t feeling soft anymore that it means I’m not. I also feel I’m getting sick but could be allergies lol. I don’t like the waiting period
