one of the at homes came back positive (the very first one.. ) the rest came back negative including the blood tests... I am a week late on my period.. which is never late.. again not stressing over whether or not I am pregnant.. just wishing that either aunt flo would come a knocking or I would get a memo from the stork.. my mom when she was pregnant with me didn't find out that she was pregnant til 3 months when she was constipated pretty bad and they did an ultrasound for blockage and found me.. is it possible that I am going through the same thing as my mom??? and has anyone else ben throught this?? Thanks!
