I need advice... Here is a picture of what glow says is my fertility window. However I've been on 3 online websites that say my day if ovulation is the 28th of February . It's 2 days after my fertile window closes(green dots) . I am scheduled to start Aunt Flo on weds. Usually 1 week prior to getting her my breasts are real tender, the right more than the left breast. However I have not experienced this soreness yet. I'd it possible i ovulated in the 28 th and could be preggers ?
