Do you think BC % stacks with % chance of pregnancy?

Say Glow tells you that you have 3% chance of pregnancy on a day, and you use a condom (effectively!) which has 2% chance of pregnancy.

Does it act like a multiplier? Does that mean you have a predicted total 0.06% chance of pregnancy in that instance?

Just a stupid question that's been bothering me. 😂

This is my first post since I started using the app in 2014... I tried to find an appropriate group; I know it's not super TMI but it is a question group so I hope it's ok. 🙂
