Really struggling...

Feel I could cry this weekend. Got another negative yesterday at 12dpo. Started trying October last year. Last week got the news that 2 girls from my village are pregnant. The one conceived straight away, and I know the other was pretty close! So so gutted, why is it me that’s struggling. When everyone else seems to get pregnant straight away? Husband goes to the doctor thurs. hoping they’ll do a sperm analysis. opk and bbt is confirming I’m ovulating. I just don’t understand why it’s not happening 😭
