I was supposed to have gotten my period Sunday, Feb. 23rd. It is now Wed, Feb. 26 and still nothing. Not even cramps to let me know it's on it's way like it normally does. I'm a lot more tired than usual, urinating more frequently, some nausia, but no vomiting. A lot of heartburn. My breasts aren't tender but my areola's are darker than usual, and they seem to have gotten bigger. I'm also having constipation.
