i am 5months pregnant and constantly hungry. i recently had a full urinalysis and my doctor told me i have a UTI . after lunch and taking my meds, i couldnt keep my food down and 5 minutes later i basically threw up everything i d eaten. today morning at 10am while at work my heart started racing heavily, my vision became very blurry, sweaty in the palms and forehead , short of breath, nauseaus and weak at my knees. i almost fell over. lasted about 5 minutes. i tried calling my OB/GYN but he wont pick. probably busy now. what could be my problem? im hoping so much its not pre-eclampsia . please help
