I need some insight, all these baby bumps got me feeling blue 😥

I'm about 8 weeks today. I don't have an ultrasound scheduled till June. 22. I'm getting so worried that my baby isn't in there because it seems like my belly hasn't grown at all and I see other women on this app posting cute little bumps who are earlier than me. I mean I've been bloating here and there and my boobs are swollen and tender. But idk, i just feel so not pregnant it's making me sad 😥 Am I freaking out? Someone please give me some insight!!!!!
