Last month I was a few days late and the whole time I was trying to not get my hopes up. Then that bitch AF showed up. Now here we are in May and AF isn't due to make an appearance for almost two weeks. My fertile window is just now closing. (I think). Yesterday and today I have been suffering from some of the sorest boobs I have ever had - even though I didn't sleep on my stomach last night. Like, they feel heavy and full.... could this be it? Should I get one of those early detection tests? Or should I wait until I'm actually late before testing? Thoughts??
