I need advice....

Yolanda • Mexican🇲🇽 Wife💍 Mom of 2 boys👦🏻🧒🏽 Baby #3 due Sept 2019🤰🏽

Ok so let me just start by saying this is pregnancy #3 and by now I should pretty much got the hang of this or so i thought. My first 2 were great other then with my second the last 3 weeks i was in the like very early stages of labor and felt like i got hit by a bus in my lady parts but other then that great. This time everything is different from beginning to now everything is different but to why i need advice. So the last few days ive either been nauseous or throwing up getting hot flashes and everything i eat makes me feel like im gonna puke my brains out. Well today the sensation to pee woke me up so i swing my legs over the side of the bed and go to prop myself up and the moment i try i get the sharpest pain in my lower abdomen and in my lady parts now this was at i wanna say 9am and all day ive been having period like cramps in my front and back with Braxton Hicks congratulations their not regular or timetable the pain isnt increasing or decreasing and i feel like i have to poo and cant ive been drinking water ive takin Tylenol ive tried laying on my left side ive sat in the tub twice and nothing is working to get this to stop and im really not trying to go to the hospital to be sent home. What else can i do ????
