Positive OPK 5DPO

Brit

I normally O (ovulation) around CD (cycle day) 17. This month I started testing around CD (cycle day) 9, got a positive on CD (cycle day) 11&12, and peak on CD (cycle day) 13. I am now on CD (cycle day) 18 and I’ve started to get peak again. Could this be a sign of early pregnancy? I had negative OPKs everyday post ovulation until now. Once before I’ve used an OPK (ovulation predictor kit) to confirm pregnancy but that was only a couple days before AF. Normally my luteal phase is a little short and causes me to have chemical pregnancies. I’m praying my early ovulation this month will help my bean stick!!! FX
