Hello, Welcome to HCM, I am Dr. Das
Look, whatever is the cause of this delay, pregnancy
should be excluded first.
For that she should do a home pregnancy test. If the pregnancy test is negative, you should do an ultrasound
of whole abdomen to look for any abnormality like polycystic ovarian syndrome
So, do a home pregnancy test and after that you should consult with a gynecologist for further management.
