Go see your Doctor.
Before you can calculate your ovulation day, you must first determine, the date of your last period's first day and you need to know your menstrual cycle. This two information is needed in order for you to calculate your ovulation using an ovulation calculator. The date of your period is not enough information, to calculate ovulation.
To calculate for the exact ovulation day, you need to use an ovulation calculator. But first you have to know when is the date of your last period's first day and your menstrual cycle, before you can calculate your most fertile period. You can also observe your cervical mucus discharge if it has a consistency similar with a raw egg white. When your ovulating, it should look slippery and clear. You may also use an ovulation kit, which is a precise method of determining the most fertile days.

Clearplan ovulation tests are used to help a woman tell when its best in her cycle when she is most fertile. You count two weeks from the start of your period and start using the tests and it will tell you when your two most fertile days are, to try to conceive a baby.
Ovulation cycles can be calculated using simple formulas based on your current menstrual cycle. I would visit WebMD to find out more on these ovulation calculators.

You can get hormone tablets from the doctor which will stop a period for a wedding or holiday. You will need the same checks you would have if using oral contraceptive but they are not birth control pills and your period will come normally within a few hours of stopping them.
If you are really concerned then I would suggest using an ovulation prediction kit because they tell you when you could ovulate.
As long as you aren't nursing anymore, you can start whenever, here's the catch. If you start your birth control right after your period it is effective almost immediately (check with the brand of pill you are using) because ovulation hasn't occured yet, if you start the pill any other time it is not considered effective until after your next period as ovulation may have already occured thus you could become pregnant, again.
