I was five days late for my monthly period when it finally came it only lasted just two days. I was also light. The day that I stopped, I woke up was really dizzy every time I laid down the room would spin and it will stop it would be like that all day. I even feel motion sickness from it I ended up throwing up once. It's going on two weeks since that happen but everyday since then I've been feeling dizzy a little sick my boobs will hurt I've been feeling crampy and moody and my back will hurt off and on and I feel and look bloated. I finally took a test and ended up negative. But my next period isn't until March 16th. Can I be pregnant even with my test being negative?
