It sounds like you could be pregnant. Some women have all the signs & not be prego & then some women have no signs & still be very prego. It just depends on your body. Everyone is different. But because you are late on your period, I would try taking a pregnancy test. By now there should be enough hcg in your urine to determine if you are or not. You don't even have to get an expensive one. They have them @ the dollar store for a buck. Good luck! Hollie
