Feeling down today :/

I do not know what my deal is tonight but I am feeling really bummed. 6 days till my next cycle and I hate cause I can never tell if I'm pregnant or not cause I don't have symptoms or the ones I do have are very close to pregnant symptoms. I want to be pregnant so bad and truly feels like it's never gonna happen. I am blessed with an amazing 3 year old daughter so I am lucky. I just want another baby so bad,a sibling for her and cause want another one.
