Trying not to stress too much about it. I'm BFing DS who is 15 months, periods have been irregular for a while now. Last few cycles were 24, 27, 38, and 25 days. Today is CD27, no pms yet just some uterine twinges and pregnancy symptoms when I look for them 😉 I think I o'd around CD15-18ish due to EWCM. BD'd around then. Test today was negative, but the test expired last year. So when would you consider yourself "late" and phone the doctor? Thanks!
