Really showing early on??

So I'm 10 weeks +4 and I am obviously showing. Like more than people who are way further along. This is my first pregnancy. I'm 5'5 and normally around 140lbs. I haven't gained much 'weight' but I can no longer fit in any of my jeans. I'm just wondering if this is normal and I'm crazy?! Like even strangers can tell & we haven't even announced yet, lol! I just popped out like crazy this week. Hooray for maternity leggings 😳😉
