I just want to second everything Amanda said...lol. I also ovulate earlier than "textbook"...usually about 10-11 days after the first day of my period. And I also got an LH surge for three days. The month I got pregnant, we BD'd the night before I had the surge, and the day after. Not sure which time "hit the mark", but I suspect it was the night before the surge...so I probably ovulated within 24 hours of the first detected surge. Anyway...it's all a guessing game and nothing is written in stone. But, don't be discouraged. You are definately not too old to get pregnant. I'm 40, and I'm 22 weeks pregnant...I'll be 41 when the baby is born. So, just keep trying! It will happen...good luck!

Hi there. We are about the same age, and I too am trying to conceive..it can be frustrating. It can sometimes take us a bit longer then our younger ladies, but we can do it just the same!! A couple of things..
In a perfect world, we would all ovulate 14 days before our period. However, with most of us that doesn't seem to be the case. For example, up until recently I always had a 28 day cycle..like clockwork! I was using OPK's and I would get my positive around day 11 or 12. I would start BD'ing (baby dancing) the day I got my positive, then every day for 3 or 4 days after). I got pregnant 4 times this way, although sadly I lost them (don't let that scare you, my situation is unusual!!). My cycle has changed in the last few months to about 25 days. This month I got a positive on day 9. So we are all different, and it can even change a bit from month to month. You want to have at least 10 days between positive OPK and period, otherwise it can make it tough to get pregnant.
Now, the OPK. If you are using the 2 lines type (it sounds like you are), it is not positive unless the test line is as dark or darker then the control line. You will usually ovulate anywhere from 12 to 48 hours after you get a positive for the first time. The average is 36 hours. BD every day from the first positive for 3 or 4 days for your best chance. I sometimes keep testing after my first positive and have stayed positive for 2 or 3 days. It is possible to ovulate and stay positive for a bit, so don't let that worry you. If you want to not drive yourself crazy, stop testing as soon as you get your positive, and just get busy!!
My best advice is to ignore that on line calender..we are all not "textbook". Use the OPK, watch your mucus and don't use any lubricant. I also use a product called preseed...you can find it at preseed.com, that I swear by!! (many others here use it as well). It mimics the fertile mucus your body produces around O time, and can help those sperm get where they need to go!
Good luck to you, I wish you the best!! I know it's frustrating, but many here your age and older have done it, and you can too!!!!
