My husband and I have been TTC for about five months now. We've been charting and the app has been very helpful- but we're not having any luck. I don't know what to do. I feel so saddened and discouraged- like something is wrong with me, or with us. I try to talk to him about it and he just tells me it will work out in the end.  We're both relatively healthy, I just don't know what to do. I'm feeling overwhelmed with disappointment. I mean- are we doing something wrong? I mean- there are people who have unprotected sex once in their life and conceive a child- how is it I can't get pregnant after five months?
