I wanna scream! My cycles are every 28-29 days with a 30 day thrown in about once a year. I was due to start on Thursday or Friday of last week! Nothing yet! I had some cramping last week that made me think " Im starting today". But no! I took 3 tests and each time. I only missed a period once in my life besides because of pregnancy. And that was about 9 years ago! Could I have stressed myself out so much about getting pregnant that I shooed the witch away??
