Am I still pregnant? 🤔

Ok so this might sound dumb ....but is it possible to loose a baby AFTER 12 weeks with no signs or symptoms of loss at all? This is my third pregnancy and I just feel weird. I do not feel pregnant at all and I am almost 16 weeks. Boobs have never been sore or grown, I don't feel movements, I haven't ever had to pee more than I normally do, hardly gained weight, and my chunk is still flabby. I was bigger by now with my last 2 pregnancy and I was way more sick during those and struggling to gain weight. I completely forget I'm even pregnant sometimes and I just don't feel like that's normal....at least not for me 🤔
