TERRIFIED

Hey guys, I'm slightly terrified. Maybe more than slightly. My mom hit menopause when she was 36. Not perimenopause. MENOPAUSE. No periods, nothing. There's a strong genetic link in age of menopause between mother and daughter. My hubby and I want 6 kids, and we've been trying for 2 months with no luck so far. I'm 21. When does fertility decline if menopause comes so early? Is there any hope for me?
