Help! Warning tmi. But please help.

Hello there!

So I’ve been on birth control for about a year and a half. About 6 months ago I changed from the patch to the pill bc my body stopped accepting the patch hormone and I bled for like two months. My long term boyfriend and I ended things 4 months ago and I decided to stop the pill this last month bc I wasn’t really anticipating having sex. Well, I did have sex on multiple occasions last month where the pull out method was used hopefully as correctly as it could have. But I am now 8 did late on my period. At 6 days late I took an at home pregnancy test which came out negative and last week I was experiencing what I thought was a yeast infection. And yeah..... someone please tell me I’m not pregnant.
