Stomach ulcer but taking pred

I've just messaged my doctor, hopefully I'll get in this week. I'm just wondering if anyone else has taken around 7.5mg of prednisone for a couple months and gotten a stomach ulcer? If frequent heavy NSAID use can cause them, but you have to taper down with Prednisone, what do you do? I took 10mg for a couple days cause I had a bad flare and needed to work an event. I went back to 7 today, but noticed the pain when I ate dinner. I'm quite freaked out tbh and just want to know what to maybe expect?
