Put my mind to rest

I have bad pregnancy paranoia!!! I need someone to put my mind to rest. I had sex on 1st September whilst on bc and using condoms. I took pregnancy tests at 5,6 and 9 weeks after (all negative) as I thought this would help me to stop worrying (clearly not.) I have had 2 withdrawal bleeds since and recently I stopped taking the pill (I decided that sex wasn't right for me at this time) and have just had a natural period. So please confirm, am I pregnant? 😣
