I'm 15dpo in normal terms and 10dp5dt in IVF/FET speak. I had some spotting on Tuesday/Wednesday which I think must have been implantation bleeding followed by very very light brown discharge in the days since. In the absence of my period yesterday I took a test and it was a faint positive. I took another two this morning - first response and clear blue digi - first response was slightly darker and clear blue was pregnant 1-2. I went for a blood test and the HCG came back at just 9 and my progesterone a pitiful 13.5.... I've been advised to start taking progesterone and also been given some HCG injections. I then have to go back for another blood test Wednesday.
This all feels so pointless. I just did another test this afternoon prior to my HCG injection and it's similar, possibly fainter than the one I took yesterday afternoon and definitely not as dark as this mornings.
I'm sure I'm just prolonging the inevitable. Be honest with me... there really is very little hope (if any) here isn't there? 
P.s. My boobs were sore until this morning and much much less so now
