Okay, my last period was the 18th of December. It was irregular because it was a week early and rather light. I ovulated January 6th. I have a regular 28 day cycle, although last month messed me up. I should be due for af January 15/16. Yesterday I had mild nausea, today it's been full blast. I've also been expierencing mild abdominal aches/twinges, too light to be considered cramps. This is how I felt back in October when I was pregnant, but resulted in chemical pregnancy, also the same time frame. Could this be the same scenario? Should I test this weekend or wait until the 20th? Just seeking opinions on what you would do/think.
