Hi, I have always had a regular period being that I ALWAYS start in between day 27 and 29. This month, i was 3 days late for my period which was very odd. When i did start, i had a very light amount of pink/brownish blood. The next day, i had a medium / heavy flow of normal colored red blood that last all day. It stopped after that day. Two days later, out of nowhere, I became extremely dizzy and hours later, ended up having severe nausea, sensitivity to smells, vomiting, and chills that lasted all night. The next day, i was weak, but the vomiting subsided. I m officially 7 days past day 28, and through out these last 7 days, 6 urine pregnancy tests taken in the morning have come up negative. Advice please . . .
