Can clomid (clomiphene) help my gf get pregnant she been trying for 4 months and nothing do you think that would work this time?

Too early to try: Infertility is defined as inability to conceive after one year of trying. If your gf's cycles are regular, she has no history of stds or pelvic surgery keep trying. If she has a history of any of the above she should see her gyn.

Yes: It can certainly help. It has more benefit in a woman with irregular periods. So an evaluation is usually beneficial before taking it.
