Early Pregnancy Help

I took a pregnancy test (okay 3) Wednesday morning at 11DPO and got a (3) positive. I took another two this morning at 13 DPO and the line is not any darker. Am I crazy to be worrying? Normal? My period is due today or tomorrow.

There is a chance I’m 1 day off on ovulation so it could be 10DPO and 12 DPO with my period being tomorrow or Sunday. I just use opk not bbt.

I know there is nothing I can do and I literally just have to wait but I would love some stories from you ladies.
