I took a hpt this morning and negative. According to different charts and stuff, AF is suppose to show on May 21st or 23rd. Yet I get nausea throughout the day....but not sure if it is some type of flu (have diarreha also ~ TMI). How early will a blood test be able to tell you if you are pregnant or not? I am thinking about getting one done, but don't want to waste the money if it isn't going to be right anyways! This is also my first cycle after having a m/c in March...so would that make things a little off?? Any thoughts or advice would be greatly appreciated!
