need advice please!!

I have been showing faint test lines on my opks for a few days before I got a strong dark positive test line Monday 1/30 which went back to a faint test line Tuesday morning. I am STILL getting positive opks test lines Friday and Saturday, had a vvvvfaint line on my pregnancy strip Friday and yesterday then no faint line on my test strip this morning and my first response came out negative. My af is due on Thursday the 9th and if I ovulated Monday I would be at 6dpo....could the pregnancy tests be false negatives since I'm still getting positive opks and I know those can detect early pregnancy or am I just going crazy!?! Someone please help! I need some advice I'm going crazy 😖
