need help...

hi girls I need (**Advice**) idk what's going on but here its the story. on October 19 I had intercourse with my partner. on the second week I've been sleeping a lot, my breast hurting a lot with few cramps. on this 17 of this month I had sex again with my partner. (**we always do the pull out method**) today I went to do per. the water was normal and when I cleaned myself the paper had light pink. been going to the restroom more often than usual. but nothing else anymore.**) my period is until next week. so my question is... is my period early, or was it implantation?
