Days past ovulation

​I didn't actually BD during my fertile week this month. But I did about a week before it. And after that this headache started. Cervix is high soft and very tightly closed which is unusual for me after ovulation I had a bit of and awkward period this month too where it would start and stop. It wasn't really a flow and only lasted 4 days I'm not going to test unless I miss AF cuz I don't want to disappoint myself. But has this happened to anyone else before.
