Mama, please ask your OB directly about this, lalo na since you're only 5 weeks pa lang, kailangan mo ng professional guidance para sa safety mo at ng baby.
I understand the worry, pero ito talaga ay medical question na dapat sagutin ng doctor mo personally based sa iyong case. A few of us moms have had medicines prescribed during pregnancy, pero bawat situation ay different, kaya hindi ko dapat mag-assume. Better safe than sorry, diba? Just message or call your OB as soon as you can para sa peace of mind mo. Take care, mama!
