Trying this weekend!

Eudina
So last month Glow was SPOT ON with predicting my ovulation so with the help of preseed, soft cups, and our donor, my partner and I are inseminating this Saturday. I'm so so so afraid that it won't work. There are so many stories of women not getting pregnant their first time and so many stories of women who do. This is our first time trying and I want so badly to see that BFP in 2 weeks. We want this so badly. We are ready to start our family. So! Any hints, tips, tricks that anyone can suggest to up the chances. If I start vitex TODAY...will it help. Any stories you beautiful women want to share to ease my worries. About me...I'm 36, been pregnant twice and lost both to miscarriage but wasn't trying with those so I wasn't so focused on being healthy and was in stressful dysfunctional relationships. Today I'm healthy, taking all my vitamins and eating as well as possible. 
Thank you for all and any input!
