Ok, here's the best advice I can give all those trying to conceive. Get an exam, start taking prenatals, and relax. Get an exam so that you can have peace of mind that all is healthy and in working order for when you do get preggy. Then you don't have to wonder " what is wrong with me", which adds stress to you and your relationship. Second, start taking prenatals and living like you are preggy. That when, when you do get preggy, you will have everything in order. You will have a healthy start for you and baby, and won't have to regret doing something that you did before you knew you were preggy. Third, relax. Stress is one of the biggest deterant in a couples effort to achieve pregnancy. Now, as far as your most fertile days and the such, this all depends on your cycle. Every woman's cycle is slightly different. The estimated ovulation time for a typical 28 day cycle is about 14 days from the beginning of your last period. So right in the middle of your cycle. There are only a few days in which to achieve fertilization, and therefore there is a fair amount of lucky timing that plays into conception. There are ovulation predictor kits that you can buy at the store to detect when you are ovulating. Also, you can start charting your basal body temp to detect your ovulation as well. (
Ovulation Calendar and Ovulation Chart - FertilityFriend.com is a good place to go for this) Please also keep in mind that it takes most healthy couples up to a year to achieve pregnancy naturally. After a year, it is suggested you get testing done to make sure there are no problems. Of course, this timing also depends on what kind(if any) of birth control you used in the past, and how long ago. Its just a try try again kind of thing. I wish you the best of luck and hope you get your wish soon.
