feeling down today :-(

I'm feeling really down today about everything especially not being able to get pregnant, 18months off the pill and nothing :-( it's weird because I don't feel like I want to rush but I want to know that I can conceive if this makes sense, also I think I'm super sensitive because I'm due a period so I'm grumpy and sad, currently it's 2pm and I'm curled up in bed feeling miserable arghhhh 🙈🙈🙈 xxx
