So confused... I normally have between 37-42 day cycles and this cycle I have had about  7 days of dark brown spotting enough for one liner a day (like dark brown discharge) and now starting day 8 it has turned pinkish/red (I also bd last night). Haven't had any other symptoms other than constipation off and on - which I have read can cause spotting. Not sure if I should even bother testing? Only on cd 30 today. Any one else experience this?
