Hi all, I completed fresh embryo transfer and got a faint bfp at 5dp5dt. Yesterday I started spotting a brown discharge and mild cramping which had continued today. Is it not too late for implantation as I have had a bfp for a couple of days? Could this be the start of a chemical ? My odt is two days away but the brown spotting has me worried. I know time will tell, just would appreciate peoples thoughts?
