I had sex and took a plan b the next day. I was 21 days late and just finally got my period. I was taking the clear blue pregnancy tests and all were negative. Took a blood test a week ago and it was negative so I realized I was fine. I wanted to make this post because I was freaking out when it hit 14 days being late and I was trying to see if anybody was going through the same thing but nobody was. So if you come across this I hope it helps and don’t stress if you took a plan b !! ❤️
