I NEED TO POO!!!!

Hannah • 5 beautiful children 14 angel babies pregnant and shooting for #6: the last one
I am almost 9 weeks and I cannot poo!!!! I have upped my fiber intake and water intake. I have been trying to be more active and I am still so backed up! The gas pain is terrible. I don't really wanna do any kind of stool softener because I have a sensitive digestive tract and those things always give me diarrhea. Any advice please!?
