I recently receive the H1N1 vaccine on this past Thrusday. I'm normally a 29 day cycle person for about a year. I recently had a laporoscopy 7 Oct 09. I was expecting my AF on 2 Jan 2010 and now, a few days after the shot, today I'm 5 days early on my AF? People are telling me to test but I don't know. Past two or three days, I've been nauseated and feeling sluggish. Can someone help??!?!
