8mos weird feelings

8mos. na po ako and this mornibg I feel nausea and vomitting, until now na 4:30PM. Hindi ko po alam kung normal po ba ito and aside from nausea and vomitting, ang init po ng pakiramdam ko. At masakit na din po abg tyan ko pag nakahiga at nag iiba ang position ko. Can anyone here suggest kung ano po pwede kong gawin. Kung normal po ba to? Next month is my due. I'm feeling weak right now.
