A 30 years old married woman has a 4 years child now she is willing to conceive again but there is no pregnancy at all. She is not overweight no PCOD on investigation, her AMH level is normal. No other abnormalities on investigation like thyroid or blood sugar. She had taken oviflo for 6 months which she stopped now since 4 months.

What should be the treatment for her. Should I suggest her hysterosalpingogram. what should be the line of treatment for her?
