Halu mama! Aiyoh, this is actually quite common in first trimester, hormones everywhere lah, progesterone making everything slow, then you get constipation followed by the runs. But since you're alternating between cirit-birit and then 3-4 days nothing, I'd suggest checking with your gynae or doctor just to make sure everything's okay and you're not dehydrated (which can be risky in pregnancy). Stay hydrated, eat lots of fibre, and don't stress too much, this phase usually settles down after the first trimester passes!
