So basically I am really struggling. I am currently as of today 11dpo. I have a short cycle and my ovulation is late on. So my period was expected between the 16th to today still no period. But still no positives. When am I supposed to test. I saw this but I'm not that many days past ovulation when I miss a period. Do I test tomorrow is 1st day of missed period. Or do I test on the 22nd when I'm 15 dpo
