How do I tell my SIL who is also trying?


I'm almost 6 weeks along now, and I don't know how to tell my sister in law! She's been doing <a href="">IVF</a> with her husband for baby #2, but they've had 2 failed rounds so far. My first month on clomid, I was so sure my period was coming, but I ended up getting pregnant. I have my ultrasound on the 21st and want to tell our families soon after that, but I want my sister in law to know first so she isn't thrown off, you know? I want her to be prepared and I don't want to shove it in her face. I need advice! I know she will be happy for us, but I know there's a sadness to not being "the one" pregnant.
