    Trying to conceive... need advise!!!

    Hi I am 35 yrs old. Me and my husband trying for our second child for last 4 months. I just got my period again this month Feb 9, so disappointed. My ovulation varies between 24-27 days, my first days of period for last four months :
    October 30, 2012
    November 26, 2012 : 27 days cycle
    December 22, 2012 : 26 days cycle
    January 15, 2013 : 24 days cycle
    February 9, 2013 : 25 day cycle

    Being frustrated by this irregular cycle, in after January period I bought the "Clear Blue Digital" ovulation kit. My period was Jan 15-Jan 20, so I start testing started Jan 22 once a day everyday around 2:30PM. Got my first positive on Jan 24, so we intercourse Jan 24, Jan 25, and Jan 26.So my questions are :
    1. I test jan 23 not position, then 24 hrs later jan 24 got positive. The box says ovulation may occurs 12-36 hrs later. What if LC surge was actually 23 night, and by the time I tested positive again 24, the ovulation done. Should I test every 12 hrs?

    2. After the positive test how many days a women can be fertile?

    3. I was thinking intercourse exactly 3 days after my period ending, is it a good idea or that would be too early for the sperm be alive?

    4. Could pls give me some suggestion about this month ovulation and fertile period based on the calender I provided above. Yes, I am using the webmd ovulation calender and all sort of different apps, but still confused.

    Thanks in advance. I am in distress, pls provide me any kind of direction and advise. Thank again!!!

    Dear An_250343, I think that you are on the right track with the monitoring that you are currently doing. Normal ovulatory cycles are between 27-35 days most of the time. Situations that increase the suspicion of a problem with ovulation include short cycles, long cycles, cycles that are variable by more than /-1 day and short luteal phases. The luteal phase is the length of time from the positive OPK until the first day of your next menstrual period. Exceptions to these rules do occur. No one knows for sure when ovulation occurs but it is probably between 40- 45 hours after the LH surge. The LH surge appears first in the bloodstream and then later in the urine after the LH hormone is filtered through the kidney. One of the key principles for timing intercourse is to understand that the sperm can live for days In the female reproductive tract and eggs are probably receptive to sperm for only about 12 hours. Therefore the sperm need to be in the female reproductive tract waiting for eggs before or close to the time of ovulation. Throughout most of the menstrual cycle, sperm cannot get into the cervix and upper reproductive tract because of the very dense cervical mucus. As the estrogen rises before ovulation, the water content of the mucus increases. Somewhere 3-5 days before ovulation the mucus develops and egg white consistency, becomes very inelastic and for the first time sperm can gain access to the cervix its elaborate labyrinth of glands and the upper reproductive tract. When you have intercourse during your fertile window, your partner is filling the reservoir, i.e. cervix, which releases sperm into the upper reproductive tract continuously for days. Men should ejaculate, i.e. clean their pipes, once a few days before the fertile window and then You should have intercourse at least once during the fertile window. Fertility is highest when intercourse happens close to the time of the positive OPK. the reason for the first ejaculation that I mentioned above is to move the old sperm out of the way and the unhealthy sperm to the front of the next ejaculation. If men have not ejaculate for approximately 2 weeks, there may be no living sperm in the ejaculate. For example, if a woman has a 28 day cycle with a positive OPK on day 14 then her fertile window begins somewhere around cycle day 9-11 and ends shortly after cycle day 14. Men should ejaculate once within a few days of cycle day 11 and then you should have intercourse at least once in the11-14 day window, preferably closer to cycle day 14. It may be helpful to keep a calendar of your dates of bleeding, intercourse, cervical mucous changes and OPK. This can help you and your healthcare provider determine if you are timing things correctly. It is normal for it to take 4 months or so to get a positive pregnancy test. If you are close to 35 years old or older it is not unreasonable to seek help if you're not pregnant within six months. It is also very reasonable to seek counseling for preconception planning anyway and especially if you are suspicious that there may even be a subtle ovulation disorder. Good luck!
