Maybe Prego Again?

Hey, so I want to know what people think of this. I already know what I think, but I just want some side opinions/answers. 
My baby is 9 months on 01/23, and anyway his dad has never been in the picture, and I've been dating an awesome guy for 3 months now.... Well, we had unprotected sex, (stupid I know but it was the heat of the moment), but he pulled out before cumming, as I couldn't go on birth control because of breastfeeding. Anyway. That was New Year's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, and my last period was dec 19-24, and well. My period is 3 days late, but it doesn't usually always arrive on time anyway. But he asked "maybe you're prego" cause I jokingly said I was being emotional. And now that's all I can think of :( .....
And coincidentally how I found out I was pregnant the first time was due to a similar conversation, except regarding sore breasts.... So I'm not sure what to think.
