Wiped after toilet and there's blood

[horsesheep]

I'm not trying to conceive, I'm not on contraception (DP wears condoms).

According to a period tracker app I'm around the time for ovulation. I have a 16 month old dd whom I still breastfeed, I got my first period 4 weeks pp despite exclusively breastfeeding. I wiped after going to the toilet and there's pinkish blood on the paper, I wiped again and theres nothing. In my underwear was white discharge, a lot more than usual (but I was wearing black underwear). I never experience spotting while ovulating before.

What could this be?

I've only ever had it happen two separate times during ovulation. I was worried and googled it but apparently it is a thing. If you have any other symptoms like pain/pain during sex it may be worth seeing your GP. I mentioned it to mine on the back of something else but she barely batted an eyelid.
