Thank you for your question. Ipill is associated with unscheduled bleeding. If you suspect an infection that too can cause bleeding. If you have kept a menstrual diary you can show it to your gynaecologist who can help decipher if the bleeding is simply because of the ipill or other tests need to be done to rule out hormonal imbalance Another thing you may wish to consider is regular reliable contraception in addition to condoms if you are sure you do not wish to conceive just yet.
