Anyone else experienced this?

I’m 26 weeks pregnant, I haven’t had any constipation during this pregnancy at all. I was just happy to continue being regular. Well, now I’ve been having some diarrhea here lately. & everything I’ve been reading is pointing me towards pre term labor like diarrhea during 2nd/3rd trimester isn’t normal? It’s just got me worried. I have taken up eating spicy foods here lately (because I’ve craved them nonstop) & decided today that maybe I needed to cut them out period & see if that helped. I just wanted to know if anyone else had experienced this to help ease my mind.
