Pregnancy percentage going up?

I just hadn’t really looked before, but does the top left circle when you first open the app that has the date and where you are in your cycle post the percentage of pregnancy for if you had sex that day, or just from previous logs? I had sex twice over the last week, and as of yesterday it said 11%, and today I just checked (without logging anything else) and now it’s saying 27% so I’m confused. Thanks in advance!!
