I’m absolutely miserable

Ladies, I am 17DPO (confirmed with pee sticks and Ava bracelet). I have been cramping since I ovulated. And it shows no sign of letting up. I have a dull ache in my uterus area and my lower back constantly, every now and then I have kind of a sharp pain in my uterus area and I think my period has arrived but nothing is there. I tested the day my period was due and then again yesterday but stark BFN. I’m just miserable at this point and want the wait to be over, I know I’m not pregnant, I’m cranky and cramping and anxious as hell. Anyone in the same miserable boat as myself? 😫 I have no idea why AF decided to be late, I feel like my body is failing me and I’m just over TTC. It’s been a hard couple of years.
