I wasnt exactly sure when I was due on as I stopped tracking as we were ttc soo hard it wasnt happening, so I gave up!
BUT... i was getting normal period pains for about 2 weeks with no blood, usually I get heavier discharge before period, but didnt this time.
started feeling sick and did a test, think i was about 1 maybe 2weeks late, but i cant be sure
hope that helps?
