I have had semi-regular cycles for a long time, usually around 27 days but ranging from 25-29 at most. I haven't been on birth control for years and years. We started TTCing last cycle and they've suddenly gotten strange!
Last cycle: Only 22 days, started spotting on Day 22. I think I was only about 9DPO, ovulated on CD13. Have never had this short a cycle.
This cycle: I'm currently on CD27 and would normally expect AF tomorrow. But I didn't ovulate until CD19 so I'm only 8DPO.
The ovulation dates are estimates based on the CBFM, I'm not telling so can't confirm that ovulation has occurred. If you look at the last two cycles, my O dates are 28 days apart. It's just that AF started weirdly early.
Should I just ignore and hope that it all straightens out?
