3dpo and Fibro

I am 3dpo. I'm 34, and had Fibro since I was 29. My poly-family has been ttc for 17 months. We've been here before and been disappointed, but this time my stomach is hard, and I've been ravenously hungry and very fatigued. 3days late means no pain meds for me until we know for sure. 
I hate to ask, but please send babydust, or advice or good vibes to survive med-less.
