Starting to show at 10 weeks?

This is my first pregnancy and I'm certainly not one of these girls who posts picks at 4 weeks thinking they are showing already. I know baby is only size of an olive right now and bloat is real but I swear my belly is starting to show. My low belly is getting hard and firm and I feel like it's getting harder to suck my belly in. I don't feel bloated at all but I know this is a possibility. Do you think it's all bloat or could it be actual showing. I know it's not the actual baby but could the growth of my uterus be making me look like I'm starting to show? I'm thin but not super thin. I keep telling myself there is no way but why is my belly looking fuller even when I try to suck in? Possible or maybe just have to poop? Hah
