Implantation bleeding?

I need help!! I’m unsure if I have had a little bit of implantation bleeding..? I have 10 days till I get my period, I’m always exactly on date with this app. But I’ve just gone to the toilet and wiped an seen a small amount of pinkish? Blood and egg white like mucus. I’m not trying for a baby and also not preventing I had sex 3/4 days straight multiple times those days and it’s been about 1 week an a couple days since having sex. Could it be implantation?

I am going to test but I’m going to wait till the day of my expected period

Please and thankyou 😊
