Reading your history, I presume you are a case of Polycystic ovarian syndrome(PCOS).
The treatment you are taking is perfect for conceiving in PCOS.
The only thing is that you have to take the treatment consistently and as advised by your doctor.
Also keep patience as good results are seen only after few months.
Metmel is metformin
which is main drug to normalize the hormonal imbalance in PCOS.
Ubiphene is clomiphene
which is used to stimulate the ovaries to produce eggs. This function of ovary is altered in PCOS.
These two are the main drugs treating your inability to conceive.
The other drugs oosure(anti oxidant) , ovacare(multiviatmin) and duphaston
tablet)would help ensure safe pregnancy
I hope I have answered your query.
