Positive OPK and timing

Hi guys,

So I got my positive opk (ovulation predictor kit) today which means my cycle will be 45days. However we went to BD (baby dance (sex)) last night and my OH (other half) wasnt into it, last time we BD (baby dance (sex)) was Sunday and Tuesday. I am assuming I will ovulate tomorrow, I dont know if he will want to do it tonight and I am on nights tomorrow so wont get it done then either, to be honest think he is a bit tired. Has anyone got a bfp after just BDing 3 days before ovulation?
