ovulating??

hi guys! i’m taking my pill at the same time everyday, i’m on blisovi fe 1/20. i don’t have unprotected sex like ever... but about a few days ago, we did go for literally 2 seconds & then put a condom on. I had to change my pill because of weight gain & i just finished my first month. I just got off my period 3-4 days ago but i have egg white discharge on my undies. could it be ovulation or something? i’m very confused. like i said, i follow my directions word for word on my birth control. any thing would help! thanks.
