Thank you for your query.
After stopping oral contraceptive pills
, return to ovulation and fertility
is almost always fast.
In rare instances, it might take upto 3 - 6 months.
Your past periods over the last three months, as per the dates you mention, seem to be normal.
It seems a rare possbility that you are not ovulating.
However, i would ask you to use ovulation predictor kits or consult a doctor for follicular monitoring to confirm ovulation.
Also get your husband's semen analysis
Be sexually active and physically fit, particularly around peri ovulatory days.
Meanwhile, if you fail to conceive within a year, consult a good Fertility specialist for further evaluation of your fallopian tubes etc.
Take care, and be positive
