Haha, with my twins, I started showing almost immediately in the 3rd month! But normally, for a single baby, it's around 16 to 20 weeks. If you wake up one day and suddenly can't see your feet, you've officially arrived, haha!
I just delivered recently, and in my case, the bump only became noticeable around week 18. Before that, I was constantly checking the mirror wondering when it would show. Trust me, once it starts showing, it grows very fast!
For most women, it starts showing around the 4th or 5th month. Until then, you can just wear loose-fitting kurtis or simple oversized tops if you want to keep it private or feel comfortable. No need to worry, your body will change in its own time.
Usually, for first-time moms, the bump starts showing around 16 to 20 weeks as the uterus grows out of the pelvis. If it's your second pregnancy, you might show much earlier. Every body is unique, so don't compare your bump size with others.
Yaar, honestly, everyone's body is so different! For me, I actually started showing properly around the 5th month. Before that, it just looked like a heavy lunch, haha. Don't stress, the baby bump will pop out soon!
