Is it normal to bloat like this from antibiotics?

I'm in a pretty decent amount of pain- gas, constipation, and pretty severe bloating. I started Ceftin last night (I've taken 3 doses so far) and even though I'm taking probiotics religiously and giving myself the dose in the middle of a stomach-friendly meal I'm still bloating like this. I don't feel nauseous or sick or have diarrhea but it's extremely uncomfortable and making me not want to keep taking the medication. I've taken amoxicillin twice before (this year only) and definitely didn't react like this. What should I do? ☹️ Here's a pic of my stomach right now (bloated) compared to what it's like normally.
