So my af is 3 days no show and i had two negative pt n i am starting to feel nauseous in the am. I also continue to have cramps and no signs of af. Could i have tested too early. I am usually a 26 day cycle and never late or missed a period. Last time i missed a period was when i was pregnant in 2012 with my son.  Should i wait until im a week late and then retest or should i start taking prenatal care vitamins since i know my body. Help!!
