Does this happen to anyone else?? Instead of PMS I am barely able to concentrate for 3-5 days before I get my period. (it's not psychological either because I noticed it before my first PPAF about 6 months ago and even posted about how weird I felt on FB, and then AF came less than an hour later) I also have a lot of trouble sleeping. It is REALLY REALLY BAD this month and I can hardly function the last few days esp. today. What should I do??? Any tips??
