Thanks for posting query to HCM.
Your condition seems like Post pill amenorrhea
It is common after going off birth pill.
Your body needs to adjust to get back your natural hormonal
It will take 2-3months,untill you should wait for normal menstruation
Once normal cycles start then you will be able to conceive.
If you will not get after 3months then you need to visit your doctor.
You need not worry.
Hope I have answered your question.
If you have any questions I will be happy to help you.
