I'm also 17, & I'm 29 weeks 2 days along. I got my REAL bump at about 17 - 19 weeks. I was 109 lbs, 5'3 when I got pregnant. Its different for every pregnancy though, so just be patient because once your bump comes & you can't see your feet, you're gonna miss your pre-prego body! Lol :P
Im 17 Im 12 weeks and im already showing and my stomach is hard so it doesnt look like weight gain it actually looks like a pregnant tummy. But my dr said if you are shorter(im 5 2") and dont have a long abdomen, you show earlier.
Congrats on your pregnancy. I started to show around 28 weeks. I am 17 and now 41 weeks. Ftm
I agree with the above comment, I am also 17 and I am 13 weeks tomorrow, under my belly button has pouched out abit but nothing noticable. Most girls for their first it's between 16 - 24 weeks, that Ive seen and heard about lol it depeds on your body and the baby. Congratsband good luck to you :)
Probably not for a while if its yer first...its different for everyone but I just looked like I had put on weight until 24 weeks and I was 115 lbs when I got pregnant 5"8 so I was really skinny...but its different for everyone
