I have been feeling nauseous all day for two weeks now! It started right before having my period 9/15. I took a pregnancy test a day  before my cycle but it came back negative. My periods usually last up to 7 days, but this time around it was only 4 days.The thought of eating red meat makes me sick. Everything I eat tastes weird/different. I feel a little bloated but nothing obvious. My significant other and I are TTC so I'm really hoping for the best. Should I go ahead and take another pregnancy test or wait until I miss my next period? Please respond!
