Very confused!!!

Mel • Boy April 21 💙👶 Girl due early Oct 23

Sooo I was testing my ovulation this week (had high days with no peak Tuesday til tonight). I had a short 3.5 day period 2 weeks ago. I was feeling VERY off tonight so I decided to take a pregnancy test just to see what the result would be (was expecting a BFN). I used a pregnosis one (which is obviously common for false positives). It came back with a faint line.. I very confused!! I'm gonna use a different brand before I go to sleep to see what the result is..
