condom and pill

Hey guys i have been on the mini pill for 2

months already. I’ve been on time all the time. I already have a 4 month old baby so my partner and i always take the best precautions when it comes to our sexual life. Today, we were having sex and he wore a condom (like always) and when we finished i noticed that there was a lot of “discharge” kind of looking stuff on him. We checked and the condom didnt break. Just in case how protected are we while on the pill and using condoms at the same time?
