Haih sayang, after miscarriage memang cycle boleh jadi irregular lagi-lagi kalau gestation dah agak advanced seperti 9 weeks, hormones kita still confused masa tu. A few of my mum friends pun experience period delayed sampai 6-8 weeks after, especially kalau miscarriage happened later in pregnancy, so you're not alone in this. Tapi sebab you're having morning nausea and breast tenderness, better check with your gynae or do a test to make sure, bukan nak alarm you, just to be safe je, sebab these symptoms boleh jadi dari hormonal imbalance post-miscarriage or something else yang perlu attention. Sending you lots of strength through this; I know how heavy it feels.
