why have i had pale pink vaginal discharge?

Hi, I have been on the pill now for 6months, this month I was late collecting my pill. I was due to take it on Monday and didn’t take till Thursday. I came of my period Monday and I have been having unprotected sex with my partner. As I went to wipe just I noticed a really pale pink discharge but wasn’t very much of it. Could I be pregnant or is there something else? Also I have noticed my right ovary is very hard and left side is squigy and soft. Please help as I am only 17.

how can u feel ur ovary? you’re not pregnant but if u want to confirm u can do UPT
