Mama, I totally get your worry kasi parang laging may "what if" sa isip, but since your OB already gave you the go-ahead, that's actually the best sign, they know your case best! A few of us mommies from my group chat have had similar situations and they delivered fine, pero honest lang, it's one of those things na mas comforting talaga to keep talking to your OB about it every check-up, especially if you're still feeling anxious. Five months pa lang, so marami pang time to monitor, and if something feels off (like unusual cramping or bleeding), don't hesitate to call your doctor agad, better safe than sorry diba.
