Congratulations! Senggugut kat perut memang quite normal dalam early pregnancy, especially around 6 weeks, a few of my mum friends experienced it jugak time tu, mostly dari ligament stretching dan hormonal changes. Tapi since you mentioned it's on-and-off dan you haven't seen a doctor yet, I'd really suggest kau book an appointment with your clinic or OB as soon as possible la, just to confirm everything's progressing well, especially since your cycle memang irregular jadi good to get proper dating scan. Swollen breasts lagi adalah classic early pregnancy symptom jadi tu okay je, tapi doctor check is the best way to put your mind at ease!
