Possibly pregnant?

Ma

To make a long story short, I’m on birth control but took antibiotics so this is the only reason I believe that I could be pregnant. Below is a picture of my cycle and dates of “ovulation” that I’m not so sure I trust. TMI: today I had a very large amount of clear discharge that was super clunky and I’ve had cramping below my stomach all the way across. Less cramping, more a sore feeling. What do you guys think?
