Ovarian/left uterus pain since 5DPO my BOOBS hurt

Ugh I have no idea what’s wrong, I’m now 10 or 11 dpo and I’ve had the left uterus and ovarian pain daily now

I’ve tested and all are negative

My breast are tender to the touch even through the bra.

I have no idea what’s going on

I feel lost and out. Feel like if this was pregnancy I would’ve gotten a positive by now
