Pill help

I’m on the combination pill (21 day) and have been since about January. I take it consistently and have never missed a day.

Earlier today when I wiped, I noticed egg white CM which I don’t remember really seeing before. I thought that because the pill thickens CM I wouldn’t have it. Last week my boyfriend and I were doing the deed (using a condom also) but the condom slipped off and some of the stuff came out. I don’t think anything went inside but I am worried about it, despite being on the pill also.

Does this have anything to do with it? Does this show pregnancy/the pill not working or can this be normal?
