Telling your best friend that is dealing with infertility you’re pregnant?

Lauren

My very best friend has been trying to get pregnant for 2 years. She has tried clomid, IUIs, I’ve even been the one to give her shots. I have seen her cry because she can’t conceive. I didn’t even have the heart to tell her me and my husband were going to start trying. I just found out that I am pregnant and even though I am so excited a part of me is sad because I know it will hurt her. Can anyone offer advice on how I should tell her?
