Absolutely speechless

So....a little bit about me. I gave birth to a beautiful baby girl in October. We tried for over a year with her. My husband is 40 and she is his first child. My fourth. We had a csection, and her birth was traumatic. She was a month early, and didn't breathe when she was born. They did cpr on her for 5 minutes and she finally started breathing. Thanks to god! Anyways, I'm a little freaked out because I am pregnant again!!! I honestly thought we were in the safe zone. We are extremely happy, but nervous! Anyone else have a csection then 3 months later get pregnant again??
