Eh, jangan worry lah! Second pregnancy memang lain-lain dari yang pertama, some mums I know totally skip the morning sickness this time around, especially if hormones behave differently. Tiap pregnancy tu unique, so takde alahan doesn't mean anything is wrong, okay.
The active part is fine, anak-anak kan memang demand energy! As long as you're not bleeding and no sudden severe cramps, you should be good. Sakit sikit here and there is normal jugak especially bila bawak kete or jumping around. But if you notice anything yang drastic change, like sudden sharp pain or anything yang rasa benar-benar off, just pop to the clinic, don't wait. Better safe than sorry kan.
Tunggu 9-10 weeks untuk scan is okay, but honestly, if you're feeling uncertain or anxious in the meantime, might as well check in earlier with your doctor just for peace of mind. They usually don't mind, and akan confirm everything is progressing well. Take care!
