Alright ladies, I have a serious concern. My period usually comes regularly the same time every month, as it should. Some of you are probably like duhhhh chick thats how they work. But mine hasn't always been that way. I used to be super irregular. Yet the past 8 months or so they've been really good and on schedule...except for this month. I'm 10 days late. Now I don't know whether to freak out or just assume I'm off my schedule again because my body hates me. I took a HPT tonight and it said negative. So I'm taking one more in the morning to be sure but I'm super confused. I've been feeling sick and sleeping a ton more than normal along with being super irritable and kinda mood swingy.  Am I paranoid or should I be concerned?
