ok ladies, I keep getting + OPK’s!

I got my first one last Wednesday... then some negatives in between, another + the other day, then another SUPER positive yesterday.... and yet again another + today. I know some people say maybe my body is trying to ovulate but isn’t... but I have also been feeling super run down. I (think) I’m about 6DPO and was wondering if any of you think I may be pregnant.

It’s too early to take a pregnancy test but I’m seriously wondering if maybe I keep getting + OPK’s because it’s detecting some sort of hcg in my urine. Has this happened to anyone else???
