I to have gone through that and still am trying. My husband is 23 and I am now 20. We have been trying for over a year now and two miscarriages on Thanksgiving @15wks and again on Christmas @6wks. Had one surgery and still now we're having a problem getting pregnant. We've have lots of test saying we can have kids and now we finally had my hormones tested that I'm very low on progesterone of 0.2%. Had all the signs but never knew about it until we demanded to be tested by specialist. It's hard and it does hurt but just have faith everyone is different. But talk to your obgyn, just to check your hormone levels and even a pre pregnancy physical just to be safe. There's even fertility supplements you can get at GNC, or online that are safe to take to help your body prepare its self.
I have also been having the same issue. I am 22 years old and my boyfriend and I have been trying for the past 9 months to get pregnant. We are both healthy and supposedly capable of having children but we haven't had any luck yet. I just had a doctor's appointment yesterday and she is referring me to a ob/gyn to have a full fertility work up: pelvic ultrasound to look at my ovaries and fallopian tubes, blood work to check all hormone levels and other levels that can affect fertility, and also an internal exam. Most doctors won't start any form of fertility treatment until you have tried consistently for one year though. My doctor told me it also helps to track your period and know when you ovulate. She told me during that week you should have sex every day or at least every other day, but not to have sex more than once a day. She also told me not to drink any alcohol while trying to get pregnant because you don't know what kind of affects it could have.
