I took one about an hour ago and it was not pregnant...
Could be implant bleeding? I bled dark brown blood for like 3 days a week before my period was due, I knew exactly what it was and was like oh sh*t, I waited another week to see if my real period would start and when it didn't I was like yup I'm pregnant. Took a test and it was confirmed
More information about intercourse is needed. Did he wear protection? Or did he use the pull out method?
I would go get a test because I was paranoid a lot as well lol now I am 15 weeks today lol good luck
