Cd45, high bbt and rising

PC • Mama to Cruz 💙 Kaia 💖 and Shaea to come 💗
I went to the doc on 1/15 and they did a urine test, negative. Here we are 3 days later and temps still rise, boobs are incredibly sore with sharp pains in my left one, and I get cramps like AF is about to show every now and again. Got a positive OPK 12/20, AF was due 1/4 and on that day I had some excruciating cramps so I was sure she was coming... But nada. Thinking maybe I ovulated later. 
I have blood tests being run from my appt but not for hcg, more for any issues that would delay my period. Thyroid or prolactin, etc. What are your thoughts? This is the most consistent I've ever been in my bbt.. My cover line is typically around 97.0-97.2
