So I Have Been Having Sex A Few Times A

so i have been having sex a few times a month without being on the birth control pill. my person uses condoms and also never cums inside me. i always finish him after he takes it out. last week, i was getting brownish clear jelly like discharge. there have been no other symptoms. i read online that the discharge can be due to stress and my parents announced a divorce last week. I just need to know if this is something i need to keep worrying about
