Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. * There is possibility of delayed periods after abortion due to blood loss&weakness or hormonal imbalance due to abortion. * post abortal spontaneous ovulation & conception is another possibility. *In case there is prolonged absence of menses. Treatment of hormonal in imbalance & anemia is needful after excluding pregnancy. This is important for further conception &woman s health in future. This needs to be planned after detailed physical examination ,investigations. Please consult your gynecologist. Hope I have answered your query. Let me know if I can assist you further.
