the first day of my last period was the 5th feb. Last night i started to get a really bad headache, i felt dizzy and sick and i feel the same today. I had similar symptoms with ds very early on and was sick must of been around 2 wks but the pregnancy test was negative so i assumed it was a stomach upset as a few days later it passed. I was alot more emotionally up and down with ds though.But have been feeling a little bit the same-i just feel different but im not sure whether im starting to talk myself into feeling this way or whther its real iykwim.
