My last period was March 30th, 2011 and it is currently May 4th, 2011. My regular cycle isn't 28 days, but 33 days. That makes me 3 days late. I've been having, what most women would call, period cramps but I haven't started yet. My breasts are quite sore and I've been exhausted for a few weeks now.

I don't work right now, so I don't know why I would feel exhausted. I don't think stress is an issue either. My diet hasn't changed and my period has only been late once in my life (3 years ago when I was taken off Evra, a contraceptive patch.

Should I test for pregnancy this early? Or wait a few days since I've been experiencing cramping?

I would give it a few more days as it is not unusual for a period to be off a bit now and then. If still no period after several more days, try a pregnancy test.

Possibly pregnant. More likely your stressing yourself over it and giving yourself symptoms. Happens a lot.
