When did YOU test? Any early symptoms?

I've always been a "wait til ur late"! Person. However, this cycle is different. I had a drop in temps at 6dpo down to 97.70° & Then today, 7dpo it spiked back up to 98.19° and ive been "crampy " for last few days. Like a light dull lingering cramp/ache. Less severe than period cramps. But they have Me wondering what is going on, as it's never happened before.

So.... if you got a BFP, when did you start testing? Was it negative first? (Like line progression) also, did you have any early symptoms??

TIA your insight and opinion would mean a lot right now.

(I have a few first response tests and a few dollar store cheapies) *a million thank yous!!!!*
