Sounds like breakthrough bleeding to me...
It's a side effect of birth control
pills, so nothing really to be worried
about, its just annoying!
when my friend started ortho-lo she got
her period on time the first month but
bled constantly until her period the next
month, so it's not totally uncommon. I
think it might have something to do with
the low dosage of hormones in it... You
might need something with higher levels,
but don't quote me on that... You can
always check with your doctor too to make
sure that's what it is.
