Wah, congratulations on baby number three! Honestly, it varies so much, with my first I felt movements around 18-20 weeks, tapi my second one I swear I felt earlier maybe 16 weeks because I already knew what to expect, you know? A few of my mum friends who are on their third pregnancy say they felt it earlier too, maybe around 15-16 weeks, because your uterus dah familiar with the whole thing. At 10 weeks you're still too early lah, but soon soon you'll get that flutter feeling, it's the best part! When it happens you'll know for sure, takkan nak salah dengan gas hehe.
