Mama, that's really important to check with your OB muna, some suppositories are okay sa pregnancy pero iba't iba depende sa type and reason, so please don't use anything without asking your doctor first, especially at 19 weeks. Alam ko constipation is super common sa pregnancy (a lot of my mum friends dealt with it!), pero mas safe talaga to get the go-ahead from your OB kung ano exactly ang okay for you and baby. Give them a quick call or text, most clinics respond fast, lalo na for pregnancy concerns. You got this!
