Hai sayang, honestly this is something yang kena check dengan doctor sebab ada cyst history plus the sharp pain when baby moves, better safe than sorry, kan? A few of my mum friends pun pernah ada similar concerns and their doctors just did a quick scan to make sure everything OK, so go ahead and call your clinic or book an appointment, terutama since you haven't had a scan recently at 29 weeks. Don't worry la, sometimes these things are fine but the doc needs to rule things out, especially dengan pregnancy. Just get it checked out this week if you can ye.
