Alamak, cerclage tu procedure yang agak specialized kan, memang kena monitor closely dengan doctor. Dari yang I dengar dari a few mum friends, ada yang kena cervical cerclage sebab risiko preterm labour, memang kena strict bedrest dan frequent checkups, plus some bleeding or spotting is normal, tapi kalau heavy bleeding or cramping mesti terus call the clinic lah. I'd really suggest you tanya doctor anda directly pasal side effects specific to your case, and maybe join a support group or forum khusus high-risk pregnancy, those mums paham betul-betul what you're going through since it's quite a delicate situation.
