Seeing signs every month & getting my hopes up

Is am I the only one or do other women out there see the smallest sign or symptoms & think this maybe my month? Not every month I think this buy some. After a year & a half of ttc, this month for example, I have breakouts that I don't usually get. My nipples are sore when usually my whole breast get sore & usually only a day or two before af not two weeks before. Probably just another month I'll be let down when af comes but I was just wondering if anyone else finds themselves doing this too? Getting discouraged
