My period is 7 days late and I've never had an irregular or missed period before. The last time it was irregular was when I was on birth control 2 years ago. I've been having cramps like crazy but every time I go to check, there's nothing. My nipples are also super sensitive and have been for almost a week now. I haven't had any other major symptoms yet like morning sickness or anything. I have been a little more tired lately and been sleeping in late but that's about it
