Dear Dr Q I am on day 31 of a 32 day cycle.I have been charting my bbt for a few months now,and for the past 5 days it's been pretty high.However,since Tuesday,I've been spotting what I can only describe as a pale brownish discharge.Not there all the time,just now and again.Today,there seems to be more of it....sorry.....tmi.......(yeak)....I just wondered if this is the start of af....or have heard it may be implantation bleed,but I really don't know the symptoms of an implantation bleed. Can anyone help????My temp had gone up again this morning........xxxxxxhelp..xxxxxxxhazel..xxxxx
