Ay, that's a great question! Honestly, it is possible para maging smaller or nawala na ang myoma, lalo na if it was small to begin with, a few of us mums actually experienced the same thing where ang doctor said it either shrunk or disappeared on follow-up ultrasound. But I'd really suggest you confirm this directly sa doctor mo during your next visit kasi they can explain what happened based on your specific case and what the old versus new ultrasound shows. Congrats sa good news though!
