35 considering another pregnancy
An_254917 posted:
I am 35 years old and I just recently stopped taking yaz birth control after taking it for about 4 years. I had my first period on November 23rd and the next one on December 22nd. My fertile period started on the 1st of this month (January 2014) but I had sex on the 27th and the 29th 3 days prior to my fertile period. I am not due to actually ovulate until the 6th is it possible that I could still get pregnant?
Thanks in advance
David K Walmer, MD, PhD responded:
The fertile window for most women is 3-5 days long with the last day of the fertile window being the day that the ovulation predictor kit turns positive. If you have regular predictable menstrual periods, you can often anticipate the fertile window (14-17 days before the first day of your next menstrual period). Some women will be fertile for as long as 14-19 days before their next period. What defines the fertile window is the water content of the cervical mucous. When the water content is low, sperm can not penetrate the mucous. When the water content rises just before ovulation, the mucous changes from being thick to very watery and elastic. The water content of cervical mucous is controlled by your hormone levels. During the fertile period, sperm can get into the cervical mucous and survive for days. The cervix acts as a time release reservoir for sperm so that women don't have to time intercourse exactly with ovulation The highest chance of conception is the day the the OPK turns positive. Men should ejaculate periodically so that the old sperm are cleared and the young healthy sperm are available to their partners for conception. Normally, the quality of the sperm will be good if a man has ejaculated within 5 days or so of the fertile window and then has intercourse at least once during the fertile time of the month. I hope this helps.
