My cycle does that too. I'll bleed for 4 days strait, then nothing for 3 days, then out of nowhere, the bleeding starts up again. Then it only lasts for about 2 days. I go by the 1st day of full bleeding to start the cycle. I just ignore the 3 days of no bleeding in between bleeds. Did I confuse you enough?
Thank you mommy-medic for my beautiful siggy!
