Too early for implantation right???

Brittany • Mom of 1; dog mom of 2; wife; SAHM

BD 8th, 9th, 10th, and last night (13th).

I got peak fertility on clearblue advanced at like 6 am yesterday. But then tested with clearblue digital and got negative at like 5 pm. So I’m thinking I tested at just the right time?

Last night it started with a pinch in the left side and then cramping. Then I wake up this morning to this and cramping again.

Anyone?😩

I know it so early for implantation but that’s the only thing I can think of.
