My period was due yesterday. I have never been late. (Cycles have been 25 days). Yesterday i had diarrhea and woke up feeling too hot several times in the middle of the night. More pimples than usual. Today i feel kinda depressed?? For no reason. I took a test, was neg. could i still be pregnant and it's maybe still too early to test??
Or is this some funky hormone thing?
