Testing March 17

I am 26 years old. My husband and I have been trying for about 2 months. I have skipped one month already and took a test 2/16. It was negative. I still don't have my cycle. I feel nausea, a little lightheaded, and cramps. But no sore nipples. It will make 2 months for no cycle by the 17 of March, I think I will test then if I don't get AF
