Ovulation always happens even with the pill. The pill prevented implantation. Taking the pill for years does not hurt your chances of becoming pregnant. Periods without the pill are often irregular and rarely consistent. You are perfectly normal. Average time it takes women to get pregnant with no birth control involved is 6-8 months.That being said.....Stress can hurt your chances of becoming pregnant. Just keep at, and don't dwell on it so much. Don't worry about it until it has been more than a year or two without becoming pregnant. Timing is everything. Go to www.webmd.com and make an ovulation calendar to help you learn when your most fertile times could be each month.
