Hi, welcome to HCM, I am Dr Das
Firstly, the drugs you take were some hormonal
As you have taken only one time, generally it will not hamper your pregnancy
right now. If you had taken these for very long time, then only it could hamper your pregnancy.
Try to have baby for one year. If then also you cannot get result, do a thorough hormonal profile for any abnormality and do a whole abdomen ultrasound
scan for any pathology.
