Aww congrats sa pregnancy, mama! Since your OB already cleared it, okay lang talaga ituloy mo ang Usana, marami sa circle ko ng moms na ganyan din, laging tinatanong muna sa doctor bago mag-switch or mag-continue ng vitamins which is the right move. The important thing is na consistent ka lang sa pag-take and you're eating well din, honestly! Just double-check with your OB din if may specific nutrients ba na kailangan mo pa on top of what you're taking, like extra iron or DHA, depending sa progres ng pregnancy mo. Alam mo naman doctors dito, basta documented at safe, okay na okay lang. You're doing great na nag-ask!
