Shart pain on the lower right abdomen during week 17

That kind of sharp pain on the lower right side during pregnancy can have a few different causes, some more routine like round ligament pain as your uterus grows, but some that do need a closer look. The thing is, week 17 is when your belly is expanding quite a bit, so stretching pain is possible, but lower right side pain specifically is something doctors tend not to want you to guess about on your own. It might be worth calling your gynae or heading to KKH just to rule out anything that needs attention, rather than waiting to see if it passes. Better to get checked and have peace of mind than to sit and worry at home lah.
