BBT Help ME!!!!

Okay, I know that illness can seriously affect your bbt temps. So here is my question. If I discard my temps for the four days that I was sick my chart shows that I ovulated on cd23 but if I leave them in then my chart says I ovulated on cd36. cd37 is my first day temping that I wasn't sick. so my question is should I disregard these temps and take the ovulation at cd23 or keep them and take ovulation day at cd36. I just don't know what to do. I can tell you that the chances for conception are high at either time cause the hubby and I bd'd just about every other day regardless of my fertility. In this respect even after being together for almost 8 years (for which I had been on depo provera), we are still very healthy. My cycles are very irregular due to coming off the depo. Any input would be appreciated.
