Miso usually refers to misoprostol tablets and is commonly used to terminate early pregnancy. The reason for not bleeding after taking Misoprostol tablets is usually due to the patient’s insensitivity to the medication, poor absorption, or insufficient dosing. Under normal circumstances, when using medication for abortion, the patient should experience vaginal bleeding within half an hour to one hour after taking misoprostol tablets. If the patient does not absorb the medication well or is not sensitive to it, it is possible that the vaginal bleeding may be prolonged to 2-3 hours before it occurs. If the patient does not experience bleeding after taking misoprostol, it is important to consider that the patient may have underdosed or failed the medication. The patient can take 1-2 tablets of Misoprostol at 2-hour intervals for 2-3 consecutive doses as prescribed by the doctor. If in this process the patient has not appeared abdominal pain and vaginal bleeding, it means that the patient failed to abort the medicine, does not rule out the case that the gestational sac is large and not suitable for medication abortion, it is recommended to use surgery to terminate the pregnancy. There may be other reasons why you don’t bleed after taking misoprostol tablets, and the use of misoprostol tablets is recommended to be carried out in strict accordance with the doctor’s instructions, and not to be used blindly on your own.
