Should I be worried at this point?

From the beginning of my pregnancy my doctor gave me that list of what not to eat. She told me deli meat is ok as long as it is heated before consumption. Any rare time I'd order a sub with deli meat I'd always have it toasted and ate it while hot.

Well last night I brought home a sub for dinner and it was cold by the time I got home. I was so hungry I just ate it. I assumed since the meat was heated prior it should have killed whatever bacteria my doctor warned me about. I now have this little voice though making me worry since it was a lot of ham.

I'm currently 33 weeks pregnant. Do you think it was safe and ok?
