Not sure if this is normal

Ashley
But I mean I know every pregnancy is different this is my third one and I didn't feel this way with the other two but yesterday I got my ultrasound done for them too check the organs or whatver they do but I felt fine when I went in then,while I was laying there I felt weird like if I was gonna pass out faint or whatever I felt my body temp going up like if I was having hot flashes or some crap then I get this really bad headache and I haven't been able too get rid of it and when stuff like that happens I kinda panic and I normally don't saying thing because I am the type of person that hates bad news I know I,should have said something I was just scared too could any of you ladies help me if you ever had this feeling or whatever I would greatly appreciate the advice or help
