advice helps /:

i’m new to this pregnancy thing so i’m nervous but i’ve been up for awhile now, it’s currently 1am and i haven’t been able to sleep tonight i was having bad hot flashes and this weird feeling in my chest like i was ready to throw up, i got so shaky and my heart rate shot up very very fast i was on the verge of throwing my guts out. i was taking as many deep breaths as possible but i was panicking because of the way i was feeling i was not able to keep my water down a whole lot until now does anyone know why this happens during pregnancy? i don’t want to have anxiety thinking something is wrong with me. any advice helps it’s hard doing this alone, my fiancé works a very long shift to provide for me and the baby and he gets really exhausted so i deal with it alone because i don’t wanna wake him. any advice helps on this i don’t want to scare myself!
