Gained weight but not showing..πŸ€”

My pre pregnancy weight was 120 but I was losing weight at the very beginning. I weighed about 115ish after I had lost the weight. Now I weigh 132.2 and I'm barely showing. I am starting to feel kind of concerned. I have always been kind of small figured and petite but I figured since I was gaining weight I would be showing a lot more than what i am. I don't even feel like I'm showing lol all I see is a little bloat. This picture was today at 20weeks and 2 days.
