Please don't worry. A temporary delay in periods after childbirth, even after completing a course of norethisterone, is common and unlikely to cause health complications. A transvaginal ultrasound (TVS) is a routine, safe scan to identify the cause. It can reveal: Uterine lining thickness: To see if the lining is ready to shed. Ovarian health: To check for active follicles, cysts, or signs of hormonal imbalances like PCOS. Uterine scar tissue: To rule out any adhesions from your C-section. Pregnancy: To rule out an early pregnancy. This simple scan will help your doctor determine the best way to safely restore your cycle.

Mild lower abdominal cramping is very common in early pregnancy as your uterus begins to expand. However, undergoing a transvaginal ultrasound (TVS) is highly recommended. A TVS is the safest and most accurate way to confirm that the pregnancy is developing normally inside the uterus and to rule out an ectopic pregnancy (pregnancy outside the womb), which is important when experiencing cramping. It also helps estimate your gestational age. Please consult your obstetrician-gynaecologist soon to schedule this scan; it will provide valuable peace of mind and ensure a safe start to your pregnancy journey.

Even when Cycloreg (norethisterone) is started several days before the expected period, it does not always delay menstruation. The effect depends on individual hormonal response and the exact timing in the cycle. If the body has already begun the changes that trigger menstruation, breakthrough bleeding can still occur despite starting 5 days earlier. Heavy bleeding and cramps mean your cycle has continued despite the medication. Hence, the safest step is to consult a gynaecologist promptly to check your condition and provide the proper treatment to manage the bleeding and pain.
