so I am so new to all this. I am now 13dpiui. I took a test this morning and it was a BFN. I'm so worried it hasn't worked. I keep it in my mind that it will take a few go's and my partner keeps telling me to stop being so impatient and just let nature do its thing. But for some reason I was so set on this one taking. Can i ask what symptoms some of you had in your tww? I've had some slight cramping, lower back pain for most of the two weeks, very moody (GF tells me all the time) no implantation bleeding (if it has happened) but then I've read that not everyone gets it. Blood test in two days time. So anxious of the unknown.
