TWW coming to an end

My TWW is coming to an end. I'm trying not to over think anything but these final days are the hardest. Had some crazy constipation 8dpo (which being on metformin, never happens), my boobs feel heavy, I feel more tired and haven't been able to sleep on my tummy the last few nights, It feels weird. Tonight I'm a little crampy and im trying not to think the worst. I usually don't cramp until I actually start my period, I'm hoping these are good cramps. If I don't get my BFP, I'm taking a break. Financially, mentally, emotionally and physically drained. Anyone have these symptoms and hey their BFP?
