I've been ttc for 2yrs and I've never felt like this. My period isn't due for a few days yet, but I'm having symptoms I don't usually have from pms. My boobs hurt. I'm having little cramps. My back aches. My head hurts. Everything is making me nauseous. I have a craving for cheeseburgers. I'm so tired I required help showering and dressing from my fiance. The boobs, headache, cramps, and back ache are pretty normal for me for pms, but my period is too far away from that. I'd probably only be pregnant a week or 2 now
