Can I be pregnant again?

Okay I just had a baby 2 and a half months ago (may 24 to be exact) I waited my 6 weeks and out of fright I waited an additional 3 weeks me and my child's father had unprotected sex and no he didn't pull out 🤦🏽‍♀️ once again I heard your supposed to wait a whole 10 weeks because after a baby your super fertile I checked my cycle calendar and it says those days weren't my fertile days my period came as it was supposed to but I am still afraid can I get pregnant or am I in the clear ?
