Based on those dates I would say it was highly unlikely.

Even if I'm 4 days late on this second period I'm pose to have this month?

Though they say it's possible to ovulate during AF, it's very rare. Sperm can live up to 7 days in favourable conditions, but the norm is closer to 3 days in good conditions, AF is NOT good conditions. Therefore any sperm present likely didn't survive the first day. If you hadn't aF the next day then the chances of a sperm surviving, and then you ovulating the day AF started are so incredibly low. So, even though you are late. I would say it's unlikely you are pregnant from sex you had before your last period.
