Estrogen rising after ovulation? Sign of implantation?

So today I am 6 DPO, i confirmed LH peak with ovulation strips, testing from the day after period ending to cycle day 15 when I got my peak, meaning I ovulated on cycle day 16. I am on cycle day 22 and I’ve been taking cheapies and opk’s to ease my anxiety (it helps me, doesn’t help everyone). I decided to take a clear blue advanced test after not using the bathroom for a while (I have a ton, I stocked up when we started trying) and I got a blinking smiley! Do you think that could be a sign of implantation?? I know progesterone, estrogen, and hcg rise once implantation occurs, could it be that my opk is detecting my estrogen rising before the PT picks up HCG? Trying not to get excited 😫
