I am on my 2nd cycle off birth control. My first cycle was 51 days long. I had no spotting at all until I had my period (which was fairly light).
My period lasted 4 days. Now I've had spotting on CD 10, Cd 18, and CD 21 (today). Not heavy and not bright red, either. Brown before and today kind of pink. Just enough to maybe need a pantyliner.
I'm not so worried about it... I figure my cycles are just still getting regulated after being on BC so long.
Anyone else have this? Seems kind of weird.
