I'm just so confused D:

A little back info: I have extremely regular periods and ovulation. The latest my period has been in the last year was 1 day. I have a 28 day cycle with 3-4 days of AF. We've been TTC for 6 months now. This last cycle, I had several faint positives at 14 DPO, my period was 5 days late, I felt "off". I finally got my period on March 24th-27th. I ALWAYS ovulate on cycle day 14. I'm now cycle day 19 with no ovulation and all negative pregnancy tests. Does anyone have any idea what is going on with my body???
