Bleeding after sex

 Hi sorry to bother you all but i am just a bit worried. I had a smear about 9 months ago and it was normal but i have high risk hpv 45 i have my next smear next thursday. Last night me and my partner had sex and i didnt bleed straight away but after about an hour there was a bit of pink blood when i wiped and i am still having some now. My period only finished yesterday so i am thinking that could be why it happened but i am a bit worried. What do you think?      I would have thought the blood would be brown if it was period and because it is pink that makes me think its fresh.. i am quite sore and it doid hurt at times.
