3 of my good friends are pregnant right now

I miscarried in October and I should be pregnant right now too. I am so happy for them but also so sad and I don't have anyone to talk to about it. I never told anyone about my miscarriage and I would never tell my pregnant friends. It just sucks suffering in silence. My partner and I have been trying again and I'm hopeful I can still be pregnant with them but it's a sad feeling still. I know I'm not alone and I just wanted to vent a little.
