Feta cheese??😭😭

I went to It's Greek to Me (It's a Greek chain restrauant not sure if it's all over the country) I ordered a Greek salad without feta and he asked if it was because I'm pregnant. I said yes, he said theirs is pasturetized. So I said okay I'll have it then! Now my stomach is killing me !! Idk if it's because I haven't had the cheese in so long or if it's bad :/ anyone else have feta while pregnant ??
