Hello thanks for your query. The procedure you are undergoing is called follicular monitoring. In this , Alivher is sildanefil tablet which would have been given to you for thickening of the lining of the uterus ( endometrium ). Hucog injection is to cause rupture of the follicle ( ovulation ), after which you should have regular sexual intercourse. Alivher is stopped generally after ovulation, and susten tablets are progesterone tablets meant to support the pregnancy if it occurs. The treatment is perfectly fine. Take care.
