Mine feel like that, but i'm just so convinced it's AF. If I had been paid this week I'd have probably wasted money on a test lol... meh.
Last month when I had my chemical, I didn't feel any cramps really on the run up to AF showing. Hmm. I don't know. I hate these few days, I just want it to either end now in a BFP or end now with AF, I'm sick of waiting.
