35 weeks prego help

Emileigh
I am 35 weeks prego and past few weeks I have had diarrhea and I've even puked a few times and have the worst acid reflex ever! I have been having these tightening pains in my back also at first I thought all this may be premature labor, but nothing .. Than maybe my gallbladder? But even without eating greasy foods and staying away from diff drinks ect nothing changed! Called my doctor I am currently dilated at a 2.30 and the baby is doing good! I have my next apt in two days.. They are gonna check me If nothing changes by than. Which this has been going on a good two weeks now so don't see it getting better only worse or staying the same. Well the doctor explained over the phone as long as I had no bleeding and I stayed hydrated drinking a gallon water each day, and my pains (she stated was Braxton hicks) was more than 10 an hour to call back otherwise wait till my apt Wednesday... She told me I could take some meds for my diarrhea which I took today and it's helped a bit!!!! Thank goodness!!! One less symptom I have to worry about! Also she told me to take tylonal for the pains, and I also took my heartburn meds.. Which I do everyday cause it's that bad! And today it seemed be eased up little more than has been but the back pains are still coming and going every so often, I'm guessing it's the Braxton hicks??!?? Has anyone else had back labor? I had it with my first child but I went into labor the next day so don't recall how bad it was... But I feel as though those back pains may be leading to back labor again??? Any suggestions??? My last child is 5 now so it's been sometime since I've been prego and so much has changed since and this pregnancy has been NOTHING like his! lol I have no energy this go round and seems like I've had a lot of issues and pain.
