I had my coil out on the 1st November and my last period was on the 25th October.... I'm so confused to when I ovulated all my tests come up with a faint line and that's about it :( 
Also my period isn't due for anothe 6 days and I have some pink/brown spotting since last night and today so far didn't know if I got my dates wrong? Also by basal body temp was rocketed Upto 39.33 it's usually 37 max??? Have I done all of this wrong? I feel really sick too and keep having severe headaches through the night :(
