I need help!

Hello my name is Alexis, I am a healthy 21 year old, I will be 22 this year. My boyfriend and I have been trying to conceive for over a year now and still no luck! I am starting to get really bummed out, and I can tell he is as well. Now we both have the mindset that "if it happens, it happens" but that alone can kind of get depressing also! Does anyone have any advice? Our sex life is very healthy, and very frequent!
