Pregnancy after Infertility

  Quick question for you infertility survivors: do any of you still feel jealous/angry when people you know tell you they are pregnant and it happened so easily for them? 
  I feel so blessed to be pregnant and am so grateful, but I still feel jealous of people that get pregnant easily. I feel like they have it so easy! I know infertility changed me and my husband for the better, but it was still a rough journey. Any thoughts?
