Hello, I'm new to this and I need some suggestions. My husband and I have been ttc for 3 years. We have a beautiful 4 year old daughter, so we aren't sure why we can't conceive again. We both have gone through many tests, and they came out fine. After the first year, I decided to change my whole lifestyle (eating, sleeping, exersize, etc...), thinking that would help. I have also been using a bt and opk's for over a year now, and still no luck. We went to a fertility doctor about 6 months ago, and she suggested getting on some kind of fertility shots, but I'm too scared to do it. I have tried every possible natural way to conceive again, and nothing has worked. My heart breaks every month to find out that we aren't pregnant. I feel like I've hit a brick walk. Should I give these "shots" a try? Or is there any other suggestions?
