diarrhea @12 weeks

So I am 12 weeks pregnant and I have been having diarrhea for the past 5 days i had already started to feel my tummy changing before I had diarrhea but now it feels very soft and different so i got concerned I called my dr office to see if they can check and make sure everything is ok with baby however they stated I have to go to my primary care dr I really feel like going to ER after work just to get some type of reassurance my baby is ok I have suffered 4 miscarriages in the past year this is the furthest I have made it. Any suggestions .
