Implantation time?

So last week my husband and I had sex and not 2 hours after my pelvis started hurting on one side as I’m accustomed to it hurting during ovulation.

That being said my tests were saying I wasn’t ovulating till Friday (2 days ago) we had sex a few more times between that day last week and today. Yesterday evening my tests said I wasn’t ovulating anymore despite that morning a different test telling me I was...

Anyway yesterday and today I started feeling subtle pin pricks and pressure in my pelvis, my vagina is sensitive and sore, and I have been getting weird dizzy spells and headaches which I never get. Is it too early to be getting any signs? I feel like it is and I’m just going crazy but I just can’t sit around without asking people who may know >.<
