Usually I have these symptoms for one or two days, then period. It's been over a week...maybe longer for the cramps I've been having: dull pain in my lower belly and back, but only on and off during the day. They don't seem to last long, but they've been persistent for 10 days or so.
I typically have longer cycles (6-7 weeks or so) so it's hard to say whether or not it's technically late; I let my body tell me when it's coming and don't worry too much about tracking the exact dates, although I do know my last was March 1st, because I had to reschedule my well woman's exam so they could do an accurate Pap.
Pregnancy is possible, but pretty unlikely.
C'mon, period. I give up. Come soon?
