Oof, kapit lang mama! Constipation in early pregnancy is super common kaya you're definitely not alone, a few of us in our mum circle went through the same thing, and honestly it's because your hormones are just doing their thing. First thing I'd suggest is drink lots and lots of water, add more fiber like fruits and veggies (prunes are a lifesaver!), and try to move around a bit kahit light walking lang, kasi pregnancy plus not pooping is really uncomfortable. But since you're already a week in, I think it's best to check with your OB po, especially at 6 weeks, they might suggest a safe prenatal vitamin or a gentle stool softener na okay lang for pregnancy, kaya don't hesitate to ask them pag next checkup mo or call na agad kung gusto mo ng faster advice.
