Should I get a morning after??

I had unprotected sex but like it was right the day before I ovulated and the only pharmacy in my town was out of plan b, now it’s 3 days since I had unprotected sex should I go ahead and go on a hunt for plan b in another town? Like if i knew it would work I would, but I’ve already ovulated so if I was going to conceive I already would have so it’d be pointless. (TMI) The guy I’m seeing hasn’t said anything about the fact that he came in me, should I discuss this with him? Like would he be ready to have a child or go half on an abortion? Sometimes our relationship seems very real and sometimes it seems very casual so I don’t really know how to approach it or if I should just deal with it by myself.
