Hai sayang, spotting on and off during early pregnancy memang common, especially kalau tengah ambil Duphaston, a few of my mum friends had the same experience and their pregnancies turned out fine, tapi since you're at 7w4d best to check in with your doctor just to be sure everything's progressing okay lah. Duphaston is progesterone supplement to help maintain pregnancy, so as long as doc confirms the baby's doing well on scan, usually takde issue pun.
