I was 2 days late and had unprotected sex is it still possible to get preganant when I was late. Could I have gotten pregnant after being late and I still didn't have mine yet

It is always possible to get pregnant when having sex, whether protected or not.

The possibility may be slight because chances are you had already ovulated and the egg is only viable for up to 18 - 24 hours after ovulation. But it is still possible.
