hi girls, i have a question 🙄 is it normal during the 3rd trimester to have diarrhea? i know its common to have constipation but what about the diarrhea? is it a sign of early labor? its been 3 days i have that, i am 31 weeks 3 days and dilated 1 cm since 29 weeks 6 days. i was put on bedrest, cant exercise or walk alot. i have a lot of bh at night and started to have pain in my back (mostly at night too). also lost muccus plug at 27 weeks. should i be worried or its normal? babys taking a lot of space in me now, maybe thats just my body reacting? 
thank you for your answers 💕
