Soooo my period is due 1/1 and I've been getting bfn since 12/27.. today I got a temp dip but it was still above coverline (97.5 vs97.1 during FP).. and I started cramping and spotting brown discharge. I definetly thought it was af.. but it's basically stopped now? I haven't had many other symptoms. Just wondering if this happens to anyone else and they still got a bfp? I've read that IB typically happens 2-5 days before af.: so I'm right in The window..
