15 DPO, period late and now bleeding/cramping

Has anyone gotten a BFP after bleeding around 15DPO? I know it may be late to technically have implantation bleeding but it's not in heard of. I have been having light cramps on and off and now they are more intense but not as bad as AF. It's just frustrating bc I'm usually on time around 28 days and now this at CD 32. Give me hope!
