I'm due between the 22nd and the 25th (my cycles vary from 26/28 days)... last month I test the 28th day, I was about 15 DPO and had a brilliant line, but AF came full force two days later (booo). This month I ovulated a day earlier so... If AF doesn't show by the 24th i'll probably give in!! I am feeling a little too confident about it and i'll probably just get crushed when she does show, but I never get heartburn, I'm not really a burpy person either!! OH even commented on my burping today and said it's funny cause I never burp, and I literally couldn't stop this morning. My tummy has been itchy aswell, or like, i'm itching it without realising i'm doing it :S
