so don't know if my period is coming or if I'm pregnant. my period is due sunday or monday it goes between 27 and 28 days. I have had heart burn off and on for 3 days straight, was so bad sick yesterday I couldn't eat without throwing it back up, boobs are swollen and tender, tired off and on , and sorry for the tmi but cervix is high and soft and have watery/creamy cervical mucus. trying not to get my hopes up just to be disappointed. I used opk , temped,pressed on ovulation day . I'm either 9-10 dpo depending on when I ovulated after my postive tests on the 10th.
