So af has been coming regularly every 28 days for the past while now. Usually exactly a week before I start getting cramps, sore boobs, junk food cravings (pms) it starts off slow then gets stronger till af comes. This time however I have nothing!! and af is due tomorrow. I also have a lack of pregnancy symptoms, im so confused as to whats going on. Sometimes my cycle can switch to 32 days but that would mean I should start getting some pms symptoms by now but I feel nothing. I've tried to pin point a few things I've had that aren't what I usually have; my nipples are a bit sensitive, I've had a weird tight kinda pulling feeling in my uterus when I bend over or stretch it. Slight back ache but nothing compared to pms, TMI constipation and just today I've started having a runny nose also my skin has been breaking out I don't know if any of this is making sense or if anybody knows whats going on. Im just so confused!
