I need some advice Mommas.

So I had my son two months ago, saw my OBGYN at my 6 week check up and started birth control. Already had my first postpartum period 7 weeks after giving birth. Then got caught up in the moment with my hubby about 2 1/2 weeks ago and haven't had another period. I'm starting to worry that I might be pregnant again. Could that even be possible right now with my timeline?
