It truly depends on so many factors like your body type, whether it's your first pregnancy, and muscle tone. Usually, for first-time moms, it might start showing visibly around 16-20 weeks, but for subsequent pregnancies, it can be earlier because the muscles are already relaxed. It's different for everyone.
Ha ha, with twins, I felt like I was showing from day one only! But usually, for a single baby, it's often around the second trimester, like 4-5 months, when you can really start seeing the bump. Before that, it's mostly bloat sometimes. Enjoy the small bump while it lasts!
Haan na, sabki body different hoti hai. Kisi ka toh 3rd-4th month se hi dikhne lagta hai, aur kisi ka toh 6th month tak bhi nahi pata chalta. Agar first baby hai toh thoda late dikhta hai. Second time pe jaldi dikh jaata hai. Don't compare yourself, you'll get your bump soon!
There's no exact answer, it's different for every woman. Some start showing really early, others much later. Don't worry about comparing yourself to others. If you're concerned about your progress, always ask your gynac during your check-up. They can reassure you.
