Should I worry?

Kirsten
Okay so I just had a baby almost 7 weeks ago this coming Friday. I went for my 6 week post partum appt and she said I looked fine.. I got my period back on 9-11 and it lasted until 9-16. My fiance and I had sex for the first time since my baby's birth. I got the depo shot while at my check up appt. We did use a condom to be on the safe side (we don't want any more kids anytime soon) but afterwards we noticed that it expired 1 year ago. Should I be worried? It didn't look like it leaked at all. Any insight will be helpful!
