Every time I go the bathroom in the middle of that night I have to use the bathroom every two hours almost. It's clear and doesn't smell but after when I go I have small mild pms cramps like. What is it? AF starts on the 20-22. I'm kinda all over the place this month (irregular) my fertile days were the 3rd-7th. Please help me understand this. And I did not take a pregnancy test. I have little symptoms of me being pregnant. The only symptom I have is sleeping, obviously pms cramps and pms tender boobs they come and go with the mild nauseousness.
