Spotting is very common for pill users,
especially during the first few months.
It often stops on its own when your body
gets used to the hormones. Let your
doctor know about it when you see him or
her though since it can be a sign that you
need a higher dose. In the meantime, you
can be sexually active, but you might want
to use a condom or spermicide just in case
your pill is a bit too weak for you.
For more information:
"Spotting: Reassure the patient that
spotting is common during the first three
months of pill use. Rule out pregnancy,
pelvic inflammatory disease (PID), and
other gynecologic problems. Spotting may
be managed by reassuring the patient,
increasing the progestin dose, or
increasing the estrogen dose. Initially,
try to manage spotting or breakthrough
bleeding by increasing the progestin in
the pill provided to a woman."

"Birth control pill users, especially new
users, often experience spotting halfway
through their cycle. Increasing the
strength of your oral contraceptives can
stop this from happening. Additionally,
spotting may be a sign that your pills are
not as effective as they should be,
therefore you should use an additional
method of birth control when you have
spotting."
