Worried...another baby on the way???!!!!

I just had my baby early april. I'm a ftm. When having sex recently with my husband the condom came off into my vagina when. He pulled out. It was deep in there and I know for sure that the cum came out. 😦😦😦 I didn't start bc yet either, so we used a condom. I was still doing my research on which bc to take. Just a vent ladies.
