Trying not to be jealous

Everyone I know is pregnant. Multiple friends, family members, even my twin sister. I am genuinely happy for them and I can’t wait for them to have their precious babies, but there’s a part of me that feels jealous that I’m not pregnant yet. I just want it so badly, and it’s been such a long road to this. There’s also a part of me that thinks that every time I get the news that someone I know is pregnant, it’s a sign that I’m next. I have hope in my heart. But I’m impatient and truly I’m afraid. I begin this month’s insemination in 8 days. Truly hoping I conceive! Any positive energy, thoughts and prayers would be much appreciated.
