How fertile am I after c-section?

I had a c-section two weeks ago, and the doctor said to wait 6 weeks.I feel fine and my incision doesn't hurt or anything just itches sometimes. But I swear my hormones have kicked into overdrive and needless to say me and my hubby didnt/couldn't wait out the six weeks. I don't want to get pregnant again so soon, and we dont have condoms ( plan on getting the 5yr birth implant) but he pulls out right before he s. Is it still possible to get pregnant even if he pulls out and never finishes inside me?
