Pregnant or???

For the past 3 months I've been bloated, I recently broke up with my boyfriend who I had sex with quite often, condom split once...I went to ride my horse the other day and everyone at the yard was like "congratulations on the baby" 😳 but I don't even know whether I am and don't want to go to the doctors and get let down to be told it's weight gain. I was diagnosed with bulimia a few years back and do struggle to eat still so it definitely isn't weight gain as I still weigh the same🤔 what could this be? *not on period when this photo was taken* off to the store later to pick up a pregnancy test.
