Waiting...

So this month I’ve kind of just been winging it because I felt like I’ve been putting too much pressure on myself trying to get pregnant. I’m currently 3 days late and no signs on af coming. The only difference is my emotions are kind of crazy and I keep crying at little things which isn’t normal for me. I haven’t tested yet but I will tomorrow morning with my FMU. I’m just so nervous to get a negative that I’m already sad (for no reason)... so strange. But, Have any of you had this before a BFP?
