Feeling self conscious?

So I usually am very fit/toned. I feel like I am just putting on fat and losing my muscle at this point.. what about you all? I’m only 12 weeks and don’t remember feeling this big with my first. I remember feeling this size at maybe 15/16 weeks. My dad already commented about my ass getting bigger and my sister boyfriend already commented about my cheeks getting chubby 😞. I’m hoping to get more active as my energy comes back. I know it’s a bit ridiculous and I should just embrace this but I just hear so many people in my ear about how much harder it is to come back from the second. I’ve been lucky with my body this far, I don’t work as hard as it looks like I do. So it’s just me having a hard time embracing the early changes. haha
