What do you think?

I’ve taken 5 tests today. I’m 10 dpo and expect my period in 4 days. I saw an almost invisible line on a strip test so I took a digital which read “pregnant”. In disbelief I took two more which both read “not pregnant”...I then took a first response which gave me a very thin, pale pink line. I feel like I’m losing my mind. Am I pregnant or not?
