TMI maybe? Bleeding after sex

Sorry ladies just need thoughts... So did the deed last night - more fun drunk sex but don't recall being any more "rough" than normal to cause bleeding this morning. AF is due in 7-8 days so wondering if it may have been implantation bleeding as it lasted majority of the day when I wiped after going to the loo! Have a feeling I'm just getting hopes up! Anyone else experience bleeding after doing the deed that lasts all day? Thanks ladies
