Hope of Becoming Pregnant After Miscarriage

My husband and I have been trying to conceive for three years. 4 months ago, we finally became pregnant but miscarried very early (4 weeks). We were heartbroken but excited for the fact that we finally became pregnant after 3 years. Following our miscarriage, so many friends shared success stories about people who easily became pregnant after their first miscarriage. Many people also told us that since we became pregnant, my body was very fertile and that pregnancy should happen again very soon. This offered us hope again. But our hope began crashing down every month that aunt flo made her monthly appearance. And 4 months later, I find that my hope is beginning to vanish.

We finally decided to do IUI next month, but I don't know how many more visits from aunt flo we can take.

Is there anyone out there who can shed some light on our situation?
