Surprise Pregnancy with baby #3

Helen
I just find out Im pregnant and we thought we were done with 2 a boy and a girl! 
I cried at first, wasn't sure how I felt about it. Never did it cross my mind to not have it but the feeling was totally different from the first 2 that were planned! About an hour later I started feeling an incredible amount of joy and I feel blessed to bc one a mommy again. I just feel a bit guilty about my initial feelings! Any thought??
