Loose bowels at 34 weeks

I’m only 34 weeks pregnant, and I didn’t go into labor with my first child until 40 weeks so I’m not expecting early labor-but I have had diarrhea 4-5 times this morning. I’ve also had some cramping, nothing too extreme, and my baby definitely dropped yesterday. Is this normal or should I call doctor? I don’t want to be over dramatic and call my doctor over every new symptom during late pregnancy, but I also don’t want to ignore any symptoms....
