Weird pre-period symptoms since starting TTC?

So I have only been trying for 2 months and at first I thought it was just because I didn't track my periods as closely when using contraceptives, but I'm having all these weird symptoms that I never had pre-TTC. Tender/swollen breasts, acne, cramps, spotting, nausea, headaches, backaches. I was totally convinced I was pregnant this cycle, had cramping on Thursday, then very light brown spotting since. I'm 2 days before my expected period (which had previously been pretty spot on as far as when to expect) and it started today. What gives? Anyone else experience anything like this?
