implantation bleeding

Latara

did anyone on here have implantation bleeding I think I may have... I started spotting at 11dpo I tested negative it stopped at 14dpo when I was suppose to get my period that day I tested negative.....15dpo I didn't test as they say to give it time so i waited until 16dpo I got a faint positive test which that was yesterday today I tested it got a little darker if anyone went through this when did you get your BFP how long I should wait to test again.
