It is possible for irregular bleeding to appear during the early days of contraception
and this should subside as the body gets adjusted to the new hormonal
levels. If this disturbance continues, you should consult your gynecologist for evaluation and if needed, a change of the contraception. Also, since you have discomfort around your vagina, though you are still a virgin, you would need a local exam to see the cause. Hope this information is useful. Take care.
