Pregnant?

So I am now on cycle day 32 and no period has shown up. It never fails to show up on cycle day 28. I think I’m at 12 DPO.

My bbt has steadily risen over the last two weeks with no dips.

I have taken several HCG tests that are all negative. But no period in sight.

I’m wondering if maybe implantation happened later in my luteal phase and that the HCG levels are too low to detect with the tests.

I am so anxious right now. Every cramp and twinge in my abdominal area has me running to the bathroom to check for blood. But there’s nothing.

CM is sticky and I’m usually dry right before my period.

Any insight?
