My husband and I don't use protection other then my taking the pill. I am usually really good about taking it but I just started a new job and have missed a few and been really stressed. My last period was two weeks ago but it was really short and light. Like I think I only used 3 tampons the whole time. This past week I have been super tired to the point where I have almost had to pull off the side of the road while driving. I have been getting headaches and been a little nauseous after eating. Could I be imagining this?
