I feel really big for 15 weeks 😞

I was excited to start to show, but for some reason I'm emotional about how I look today. I've gained 6 pounds in 15 weeks (which I didn't think was a ton) but I feel like I look further along than I am. This is my first, and I see a lot of people on here who don't show until way later. I haven't been eating the best and I'm trying to curb that, but this has just been tough 😞😞😞 and I know that it's possible that this is just fat still, he is still pretty low down, but honestly my lower stomach has really hardened. Did anyone "show" early with their first? I guess I don't even know if this is considered early
