Hello, I would be happy to help you with your question.
This medication is sometimes used for irregular cycles, and is reported as well in the use of medically induced abortions (i.e. using pills). It obviously did not end the pregnancy
, and the chance of harm is extremely low. I would explain to your doctor why you took this medication (for irregular cycles) and ask them to perform a followup scan in the next couple of weeks to make sure everything is going okay.
I hope that this helps and good luck!
