Long story short...we aren't NOT trying to conceive. The first day of my last cycle was October 31st. I haven't been on the pill for nearly 8 months. I know I ovulated on November 21st, which seems late in the my cycle. I have been feeling exhausted, some back pain, very cranky and weepy at times. I took a test last night...Negative. I took another this morning to make it most accurate and still, negative. But, I am now five days late, which I can't remember when that happened last. Any suggests?
