So I know period days fluctuate by a couple days, give or take, but what is considered "late"? I've never understood that and it freaks me out! Like right now I'm on day 31 of an average cycle of 30 days but, my past few months have been 27-28 days. My boyfriend and I got jiggy on my supposed ovulation day but we used protection yet I'm still stressed about being pregnant. And I know the stress makes it worse but I think we all get stressed about that right? 🙁 Help a worried sista out?
