Help do I graduate now and take prereqs after or delay graduation

Hi I need some advice! I am in my 4th year of undergrad for Biological sciences. But I haven’t finished my pre-reqs for PA school. I have pretty much used all my electives and I can graduate after next semester. I am not sure if I should delay graduation to take my prereqs or should I just get my bachelors and then do the rest of my pre-reqs at a CC or as a postgraduate certificate ?
