I’m concerned..

Anyone have the issue of throwing up water? I pretty much drink nothing but water so baby and I stay well hydrated and you know the doctors.. they say water water water. Well I have felt like crap all day.. head, hurting, burning up cause my bod temp is higher being pregnant.. but like I eat as clean and as much as possible and I try keep water around all the time. But I drank some water after waking up and it instantly made me sick and then I ended throwing it all up.. after massive cramping in my stomach.. anyone else have this??
