I need help

So 3 days ago I started cramping, like it's not sevre but it's there enough for me to feel it. I ovulated in the 5th& did the do on that day. Well last night we were fooling around && I bled a very very light pink colour and it was just the smallest amount & went away. I took a test this morning and from what I saw was a super faint line. Is it possible to get a faint line right after "implantation

Does me bleeding mean it was implantation?

(Normally sex will cause my period to start earlier than usual)

any advice?
