Hi everyone. I have been worried and I hope to get your insight on my situation. Just a background, I have been with my bf for 3 years and been sexually active during those times. We are both in our 20s. We of course use protection every time. Recently, I gave him a bj and he came in my mouth. He came A LOT but I swallowed all of it. After 20 minutes or so we had protected sex. Now my concern is, we used spit as lube. I did not think of this until after the deed. And I also happen to be on my fertile window, which adds concern. I know this because I was producing egg white cervical mucus. I am aware that this is the highest time a person can conceive. I am completely unsure of the percent of pregnancy from this. How long does sperm live on the mouth/ saliva?! I appreciate your response.
