I can't stand it that people that don't want kids can get pregnant on bc and someone who does can't...

I am 24, I have been married for 2 years, we have owned our own house for 1 year (we even bought a 4 bedroom house to have plenty of room for our hopefully growing family), we are both working great jobs in our chosen career fields, and have been trying for 6 months...and nothing... It seems like it is never going to happen... I know there are people who have been trying much longer, but it still doesn't make it any easier. I love children and have always wanted to have a few. It seems like everyone on my social media accounts have been announcing every few days... I could use some pointers if anyone could spare a few...
