Sex 1-2 days after ovulation

Ok so I need help lol I had sex Saturday and ovulated between Thursday and Friday and my bf decided that at that moment he wanted to throw baby dust lol now before I got pregnant with my 1yo I knew most I didn't pregnant but idk how different it is after giving birth a year later. My period is due on the 1st can someone tell me is it possible or have this happened and they ended up pregnant?
