Hello ,Zee.
Thanks for the query to H.C.M. Forum.
In all 18 pills ( morning after ) ,usually these tablets are combination of levonorgesterel+
ethinylestradiol.
You took these tablets in the month of June 2012 i.e almost 17 months back.
Mind one thing that there is no any side effect of these tablets at present, so don't bother.
Now question is you are not getting pregnancy?
Possibilities includes .
1 Poly Cystic
Ovarian Disease ( pcod), diagnosis can be confirmed by
ultrasound of both ovaries.
2
Hormonal imbalance , diagnosis can be confirmed by estimation of estrogen, androgen, FSH/LH ratio.
3 Follicle did not mature , diagnosis can be confirmed by study of ovarian follicles.
In my opinion consult an
infertility specialist and get his opinion.
Good luck For you Dr. HET
