Opk test line dark for 10dpo

Caitlin

I took this $1 opk yesterday morning around 10ish and took the picture immediately after the waiting period (3min) , normally my opks are lighter or barely showing when AF is a few days away , could this b a sign of pregnancy ?

I also haven’t had my normal PMS symptoms this past week , just more tired , irritable, headaches and dizzy ...

I’m going to try a HPT with FMU on the day AF is due (Tuesday)
