How I found out I was pregnant

So let’s just start off by saying I was a stonner ( not no more because you know there’s a little one growing). At the time I could smoke whole blunt and be fine , but nope one day I couldn’t even take 5 hits off of it and I knew something was wrong. So I went to the store got a test and boom 8 second after it was a BFP . I didn’t even have to wait 3 mins for the result. PS since I found out I have NOT picked up another blunt . It’s been about 2 weeks since I found out.
