Venting

I know I'm not out until AF comes, but she's due tomorrow and I just got a BFN so I'm feeling really discouraged. I have endometriosis and I know a lot of women are actually able to get pregnant, but I'm worried I will be one who won't😔 I have had so many unthinkable bad things happen in my life so I feel like this is just another thing I'm unlucky about. We've only been TTC for about 4 months but I'm already getting sad and worried..
