I'm sorry you're feeling down! It seems like when you hit that 1 year mark of ttc, your mind starts to wonder about all the bad things that can be causing you not to get pregnant. I know I did. Hang in there... hopefully there won't be any issues and you just need a bit more time, but if there are, I'm sure your Dr will work with you and get you a plan for that BFP if you need it!
We're all here for you if you need to vent, cry or whatever!
