So I have my period feb 5-11. We had sex on the 22 and for the last couple days my breats have gotten sore and fuller, I've gotten headaches, stuffy nose, high back aches, lightheaded, small cramping but not like AF. I'm supposed to have my period on the 11 according to glow, although I have weird cycles. I could have a 3 month break between cycles and once I had 2 periods in a month. Anyways, I don't normally get headaches backaches or fuller breats with AF so what do you guys think?
