Pregnant after a chemical pregnancy

Ka

Is it possible to get pregnant right after having a chemical? I had my chemical on august 13th, I'm currently 5 days late on what should be my next period. I know I ovulated on the 28th of August. I'm having nipple pain again like I did when I got my faint positive with the chemical but no nausea or anything like that. Should I wait until I'm 2 weeks late to test?
