How do I tell my friend who has struggled with fertility that I'm pregnant?

I'm in a dilemma and I don't know how to navigate it. My very best friend has been with her husband for 12 years, married for four, and been actively TTC for three. She has had two miscarriages at early stages, and has not been able to become pregnant again for more than a year now. I love her like a sister, and I KNOW she is going to be thrilled for me, but I don't want to hurt her. It also doesn't help that my husband and I are blessed, and became pregnant our first month not using protection. Yes, we're so happy, but that's just salt in the wound for her, isn't it?

Please help me with advice on ways to share my news with her. She is aware that we were planning on TTC, so that has already been established.
