Bbt question

dawn • Married ttc 👶🏼 #1 pcos, stage 3 endometriosis, MTHFR

So my bbt has remained above 97.5 I'm now 11dpo. I had a dip of 97.1 on 5 days dpo. Does this mean anything? I also have creamy cm and cervix is high firm and closed. I actually might have ovulated I had some serious pain that weekend. I had laparoscopic surgery 3 weeks ago. I have endometriosis and pcos.
