I need help!!! IB or just spotting! HELP PLEASE!

Sarah
I have been spotting 8 days now. I expect my period to start the 13th. 
I have been trying for about a year now and I also suffer from endrometriosis.. It's basically now or never my dr says. I took a test and got a BFN
I have another I plan to take the day my period is expected (unless I start my period) 
I just really need help with this. All I have ever wanted was to have children and this is my only time... My dr says I maybe have another year but that's pushing it. 
My spotting has been light only two days did I get enough to show in my underwear and every other day just when I wipe I can see it. 
It has mostly been a brownish color some days it's a little pink here and there and after sex I get a small small amount of red blood. 
PLEASE HELP!!
