I feel that I may be pregnant. My lmp was April 14th 2011 and I had unprotected sex on April 27th. I have been seeing some signs such as bloating, nausea, mild cramping, abdominal discomfort, etc. My period is due this week and I am regular every month. I'm just a little concerned because today I am having the same mild cramps and noticed a very pale pink color on the paper. This discharge is only present when I use the bathroom. Is this a sign of pregnancy?
