AF die today, but...

Chelsea
So af is supposed to come today and I'm usually pretty regular, glow seems to do well with predicting it. The last three days I've been very nauseous and nothing makes it go away. Food just doesn't seem like a good idea, and my boobs are on and off sore and maybe tmi but horny as all hell! Lmao! Oh my goodness! Anyone else have these symptoms following a BFP? I might also add for some reason I'm super nervous to test.. Also, How long have you waited before a test?
