Hi- I have symptoms of being pregnant, but not sure that it can happen. My boyfriend had a Vasectomy 7years ago and has never been tested since then. I had a period (which was a week early) on the 19th lasting only about 5 days, when they are usually around 8. I have been nauseated in the mornings (cant keep anything down but crakers) since Friday, but it usually goes away around noon.i have had bad headaches the past few days as well. Could this just be the flu that is going around or could I possibly be pregnant? I know that it is a very minimal chance since he did have the vasectomy and it was so long ago.
