Hi, I m 20 week pregnant. All of a sudden I felt very dizzy. I was preparing dinner and stood for 45 mins , i don t no what happened , I was frying some stuff in oil and my eyes started burning as if im very sleepy, was very dizzy and felt like vomating. I could not stand for any longer and was felling more dizzy with my eyes open. So I sat and closed my eyes ad drank water. After 15 mins I checked my BP which came to 92 by 67. What does this mean. Why all of a sudden. Felt very dizzy. Please help and let me know. Thanks Kanika.
