Really need some advice please girls. On the 23rd/24th/25th, I had very very light dark brown discharge sporadically through those 3 days. Crampy feelings around the 27/28th when I thought it was a sign of coming on AF very soon. Still have had no period and have had many pregnany symptoms but 2 negativr pregnancy tests!

only thing I can think that's different this month is the fact I started taking pregnacare conception vitamins and now after doing some research into them people have said they completely messed their cycle up? Anyone got any ideas because I don't know what to do.
