Anyone experienced this?

Yup - then started spotting and cramps at about 9w. Went doctor scan only showed 6w size and no heartbeat. Given meds and told to go back in 2 weeks. But within the week the cramps got more intense and started bleeding clots. Went emergency they said I was going thru miscarriage, did d&c the next day cause pain was unbearable.

Don’t worry:) if your menstrual cycle is usually longer or irregular, this can happen. Dates can change again when they do the official dating scan in a few weeks

Don’t worry! It depends on your mensural cycle as it varies between ladies. Ultrasound results are usually more accurate.

Should be fine but do consult and seek advice from your gynae
