Blood test for hormone levels.

Ciara
Hi guys, 
I have an appointment on Monday for a blood test to check my hormone levels and I am very nervous. Has anyone had a positive experience? i.e. Not being able to get pregnant, having a blood test and levels being normal and going on to get pregnant shortly after? I know it's a long shot, but I need some hope here ladies! 
Thank you so much in advance ❤️
