My sister in law is pregnant and I’m so devastated

Jacquine

My brother in law and his wife (my sister-in-law) only been married for 3 months and she’s already pregnant. I’m angry I’m sad I’m filled with so many emotions and my husband is just as upset. I don’t know what to do I can’t man up and let it go and be happy for them. I stopped my birth control in sept 2018 and it was the depo so the 3rd week when it would wear off would’ve been in December 2018. So we have been married for 1.4 years and been trying for exactly a year I’m so ugh any advice or similar experiences would be nice to talk with some one. Thank you
