Since you think you might ovulate on the early side, start trying when your period ends. Every other day is usually fine, but if you want, every day is ok too unless there were a known issue with sperm count.
When your body is preparing for ovulation you may notice a change in the discharge you experience. Often it will become more fluid, more abundant, and more clear. Although it usually is pretty evident externally, some women will find checking internally works for them. This sort of mucus allows the sperm to survive for a few days (most only about 2-3 days, some a bit longer) prior to actual ovulation, otherwise they die off fairly quickly. The egg is only viable for about 24 hours, often thought the first 12 being the optimum so trying for an exact day can cause you to miss the mark. Best odds of conceiving are having the sperm ready and waiting.
You can also check the feel and position of your cervix. When ovulation is approaching, your cervix will soften like your lips, feel slightly open, and shift higher. At other times it will be lower and firmer like the tip of your nose.
Some women notice some slight discomfort low in their abdomen usually over either one ovary or the other. This can happen just prior to actual ovulation, during, or right after ovulation. Some will find they are more interested in sex during the days leading up to ovulation. You might also experience a bit spotting on occasion during ovulation.
If you decide to temp/chart or use opks at some point, keep in mind it can take a few months of use to notice a pattern. They work well for some women, but are frustrating for others. They can be helpful in determing when you are the most fertile in your cycle and then you can concentrate more on that week with perhaps a few more sessions of bding.
Make any lifestyle changes that you know would be healthy....this includes partner as well.
Keep in mind, timing is just one factor with conception. There are a number of variables that have to be just so. This is why it can take perfectly healthy couples months of trying. Most will become pregnant within a year of trying, but some will take even longer than that.
Fingers crossed you don't have to try too much longer!
