Nightmare Weekend

Well the 2-week wait was going fine until Friday (7dp2dt) when I got lower backache and cramps that feel to me like AF is on its way. They continued all day Saturday. I pos on Saturday and it was negative. I have spent most of the weekend sobbing.
Today I'm 10dp2dt and the backache has gone and the cramps have gotten milder but I don't hold out much hope.
Beta is on Wednesday 17th.
On a brighter note we got the go ahead to buy our first home. The home we will become parents in one day!!
