Does anyone else have shorter cycles? After being on birth control for years, I got off the pill the end of September 2018 when we got married. I didnt start tracking my periods til November. Never having paid attention to this before, I know my average cycle length is 23 days. Is this normal? I started using opk's after my early January period and never seem to catch the positive if there was one. When I get a second line like the bottom test its never been dark enough. Maybe I didnt test enough times? Feels discouraging. Anyone else with a 23 day cycle, what day do you normally ovulate?
