Stealing her thunder?

my little girl is currently nearly 5 months old , I never posted my pregnancy anywhere in social media & not many people knew, both my ‘best friend’ and I had fallen out prior to me falling pregnant and didn’t know until after she was born, things are all good again, until she announced to me almost 3 weeks ago that she is expecting her first, I was beyond happy for her, until I found out last night I’m currently 6-7 weeks pregnant myself, I don’t want her to feel I’m stealing her thunder, should I keep it from her for a little while until she enjoys her own pregnancy, or run the chance of her being annoyed I didn’t tell her once again?
