I recently started trying to conceive in April of this year. Since then I have had cycles ranging from 29-35 days. They have gotten a little longer since being off birth control in April (29 days for a the first couple of cycles, then 32, then 35 the last couple). I am currently on cycle day 39. I have had brown spotting for 2 days, but only when I wipe. I took an HPT on Friday or Saturday that was negative. Just curious what could be causing a cycle to last this long, and if I should contact my local gynecologist.
