If you had the confirmation of the completion of abortion
followed by a normal period, then there is no reason to worry. The medication taken for abortion does not delay cycles; it could be another pregnancy
or a simple hormonal
disturbance. Please get a pregnancy test done, preferably a blood test
along with a trans-vaginal sonogram. Maintenance of a healthy weight and a healthy diet are essential to regulate the cycles. Hope you find this information useful. Take care.
