Aiyoh normal lah mama, especially in early pregnancy hormones memang buat bladder sensitif gila! A few of us went through this at 5-6 weeks and memang every hour kena toilet, then it settled down around second trimester, so your previous pregnancy experience was quite different but nothing to worry about. Just make sure you're drinking enough water and when you go for your scan soon just mention it to the doctor, they'll confirm everything is okay!
