Extremely confused and worried

I've been on the combined pill but my last 7 day free pill break literally only had what I would call spotting, only showing when I wiped. This Is has worried me as the past 7 day free was very light so I decided to come off my pill and have been off it now for nearly 3 weeks and have dine numerous pregnancy tests all negative but still no period. Im hoping im just stressing and am not pregnant as I have no partner and have not been sexually active sine end of September. Please tell me im just a crazy person. I don't want to bother my doctor as there busy with the pandemic but I need clarity as I suffer from Anxiety
