CD40 5dpo

I couldn't sleep last night. I'm sure it was the tea I had before bed. So I slept on the couch, under freezing blankets, and of course, temp drop this morning. Did it drop because I'm feeling better and I didn't really ovulate because my temps were just reporting my illness? Did I ovulate and my temp is reflecting my freezing ass on this couch? I wish there were no questions, and that this was all very much straight forward. Alas, onto Day 1 of Western Medicinal Techniques!
