Confused

My first pp period ended on 9/29. Im supposedly in my fertile window but my bbt is all over the place, opk’s look the same every day (relatively dark, but not positive). Cervix has been high, soft and closed since 10/1 with light watery mucous. I’m afraid that I’m not going to ovulate.

Back story: my husband had a vasectomy (mutual decision) but then I got my period and with my fertility returning we both regretted the vasectomy and decided we would try for one last baby before the vasectomy goes “into effect”. But now I’m afraid my body isn’t going to do what it’s supposed to.

Anyone have any insight?
