Hi umm I'm 22 and trying not to freak out or stress because I know that makes your period late but my periods are very regular and last about 5-6 days. Last month it lasted 2-3 days and then spotted for another 1-2 days...After that I think I felt my uterus twitch or flutter I've never felt this before..It kinda felt like how it feels when your stomach growls but it was really low were my uterus is. Now my period is late this month I'm extremly tired. Ive been feeling like I'm going to be sick but only burp and have little baby "barfs" where it comes up but doesn't come out. Also for the past two days the girls have been very..."perky" and very sore I have also been having headaches, very tired, craving peanut butter (yesterday I ended up making peanut butter bars and peanut butter pie) Does anyone have any ideas on whats going on?? Advice is very much welcome
