Getting sick?

Took my temp today at work, 37.8... Either I'm getting sick or I'm pregnant again. My temp was high 37-low 38s for about a week before testing last time. Not really expecting anything else for about a week so I guess we will see what happens. Kinda sniffling a bit, could just be a cold... But they don't usually make my head feel like it's boiling, whereas being preg last time did. I'm trying not to think too much into it but wanted to track it somewhere.
