Pregnancy??

Hey!! I really need opinions!!

The last time I had sex was the 2nd of august and I supposedly started to ovulate 4th which I can’t remember at this point. And since then I’ve been taking pregnancy test throughout this whole time! It’s September 24 and I haven’t gotten my period and the last time I took a pregnancy test was last week which came out negative!!?? And note that this is going to be my first “natural” period i have in a while from taking Plan B

PLEASE PLEASE PLEASE COMMENT YOUR THOUGHTS!!!
