It’s almost scary how similar my chart is to my BFP chart from September/October. I’m only 4 DPO today but I already have big blue veins on both boobs and the only other time I had that was right before my BFP. But doesn’t it seem too early for that to happen? Or can other things cause it?? ? I really hope and pray this is going to be it! ???
