Hello, thanks for the query i understand your basic problem is not getting pregnant. Unfortunately, it is possible to become pregnant without seeing your menses as you breastfeed. If there is already another pregnancy, then the period will obviously not come. You should do a pregnancy testing with early morning urine to confirm the pregnancy. If the pregnancy test is negative, then you will need to be put on contraceptive of your choice( IUD, Jadelle, Depo inj, etc) IF the test is positive, implying you are pregnant, then it will be an abortion you need if you do not need the pregnancy. However, abortion is controversial, acceptable in some Countries and not in others. For this, you must meet a doctor. Best regards Dr Achuo
