Usually withdrawal bleeding should occur within 3-5 days after stopping the pill, but sometimes it may take even up to a week. Urine pregnancy
tests are not so sensitive as they cannot read low values of hCG
. Instead, you should go for blood tests to check B-hCG levels, which are very accurate. The time taken for withdrawal bleeding depends up on the hormonal
status of the body prior to medication. If estrogen
levels are insufficient, you may take longer to get withdrawal and sometimes may not get it at all. Please see your doctor for further suggestions and also a sonogram. Take care.
