I just started spotting af due the 7th so I took a ovulation test and it looks almost positive when it hasn't been positive once till now , is it possible to ovulate so late literally a day before your period?? I've not had one so dark but maybe I'm reading it wrong , help please 
PS: totally new to the testing game lol
