I m trying for conceive. my last period date was 27th Dec 17 and i m having irregular period problem & PCOD also and my ovulation cycle is also late. and on 16th Jan 18 doctor did my sonography and she told me there is not follicle showed in it .. may be its ovulate and rupture. before one week from 16th jan 18 my follicle size was 15mm and endo size 11mm. now i do not know how it happened? if my follicle is not shown then we can say it is ruptured??
