Hello
You are taking medicine for ovulation stimulation (
clomifene ).
The dominant follicle size was 15 mm ( till 30th day it is also 15th mm ).
The size of follicle should be around 19 mm to 20 mm on day 14-15th at least to rupture and endometrium thickness must be around 11 mm to conceive.
In your case 15 mm on 40 th day is useless.
You are also having
pcod , so this may be the cause of
irregular menstruation , so need not to worry .
PCOS is the main cause of your problem.
Cysts are often caused by hormone changes. Using birth control pills can sometimes help regulate hormone levels so that the cysts can be taken care of.
Your gynae will likely want ( if you visit for 2nd opinion to another gynaecologist ) you to come back after you ahve been onthe birth control pills as well
metformin ( according to you medicine for
diabetes ) to if cyst is gone.
At that time doctor may suggest you to stop using medication of if indicated , you may need to continue it for a bit longer.
Once you stop the birth control pills , as long as there are no medical concerns , you SHOULDN'T have any problems in FUTURE CONCEPTION.
Sometimes birth control pills and anti diabetic drugs are prescribed for other purposes then preventing
pregnancy or diabetes.
In my opinion don't be in so hurry , rather first of all take treatment for pcod.
So consult a gynaecologist ans get his opinion ( 2nd one).
