Implantation bleeding only after orgasm?

Ok, so I am wondering if I'm pregnant. Of course I'm going a bit crazy waiting to test, but meanwhile I'm monitoring whether or not I have any implantation bleeding or other signs. I haven't, but after a self induced orgasm yesterday I noticed a very very small amount of light pink after wiping. I'm wondering if this could be a sign of implantation considering I've never bled between cycles before? There is still 8 days until my period is due, but I'd be grateful for any responses from those who have experienced this. Thanks!!
