Feeling excited but guilty

My husband and I recently found out we are pregnant with our first baby. We were fortunate in that we were only really trying for a month. We are incredibly excited about our little bean, but I'm feeling guilty as well. We are gradually telling people our news, but I feel so awkward and guilty in telling a few of my friends who I know have been trying for a while without any luck. These are wonderful women who I know will make amazing mothers, and I can't imagine trying for the amount of time they have without success. Then here I am with my beginners luck, and I feel bad that it came so "easy" for us when so many wonderful people struggle. Has anyone else experienced this? How did you handle it?
