Heartbroken

I was feeling so confident when I woke up. I'm 10DPO today. I just KNEW I was going to get my positive! I was unfortunately wrong... I got a BFN and I realized my period had started early when I wiped. I'm devastated... This month marked 1 year of trying. I can't stop crying. And my boyfriend is still asleep since he works 3rd shift. I am so sad... I don't even want to keep trying now. I feel like I'll never get a positive. I should just be happy with the 2 kids I've got and let go of the idea of expanding our family. My 2 are from a previous relationship. Boyfriend and I wanted 1 of our own. We've had 2 losses and just want to meet our rainbow. But now I'm not sure that will ever happen. Just feeling broken right now...
