When did you start showing during your pregnancy ? (FTMs)

Hi everyone!! I am currently in my 2nd trimester at 18 weeks and 3 days (Due June 25 2021). I am just curious to know when everyone began showing? Is it normal to not show for a bit longer ? I’m about 5’7 & 110LBS but I’m barely showing. I’ve been getting a little discouraged lately seeing other FTMs due around the same time as me with big bumps but it makes me happy also seeing their bellies hoping mine will come soon lol. Doctors say everything is okay but I worry a lot feeling like my belly isn’t growing and then there’s the people who constantly ask “is your stomach big yet?! Let me see it! Are you sure there’s a baby in there?!” Makes me really question things and very very sad lol. (You can also provide belly pictures if necessary, please don’t mind my mini venting ! It won’t trigger me I promise)
