persistent diarrhea at 29 weeks

hi fellow mummies, i’m 29 weeks pregnant now. and since ystd, i have been having diarrhea runs, especially after every meal. apart from the diarrhea runs, i am feeling quite okay. but i’m still worried of possible food poisoning and concerned it might affect the baby. should i go to a gp or go straight to kkh (where i have been having my gynae appts)? anyone experienced this before?
