I'm 22 and I'm kinda freaking out a little...So my period is very regular (5-6 days) unless I'm stress or I'm working at a new job. But last month I wasn't stressed and didn't get a new job or anything and my period lasted 2-3 days and then just drops for a day or two. Now this month I don't have anything and I've noticed that I've become very sleepy all the time, my breasts are very sore and very "Perky" all day and I've felt like I was going to be sick and I just end up burping and having a little baby barf where it comes up but then goes back down...I also noticed a couple weeks ago when I was sitting at work that it felt like my uterus twitch or fluttered...I have never felt that before and I'm guessing that it was my uterus because it was very low and right in the middle and I'm pretty sure thats the only thing in that area. I have also been having headaches that come and go all day and all day yesterday and the day before all I wanted to do was eat peanut butter...I mean I wanted it so much I made a pan of peanut butter bars and peanut butter pie...Can someone please give me some advice on if I might be pregnant or is my body just being weird
