Temperature very low

Zoe

I’ve taken my temp every morning at the same time and they are quite low and getting lower. I was meant to ovulate last week but still getting neg test results. At first I thought I got a positive result but the lines wasn’t as strong as the control line. I’m thinking maybe because I only started temping I ovulated a few days early and missed it when I was waiting for my thermometer. Anyone else have lower readings normally. Not sure if it’s normal?
