Just in case you ovulate early in your cycle, start on about the 10th, and have sex every third day (or not more often than every second day) through the 17th or 18th.
if your cycle is roughly 28 days it will be roughly 14 days after the first day of your period, not after, so from your dates it should be the 17th. Best of luck
that depends on when you ovulate most women ovulate about 2 weeks after their period but it varies it depends on how long your cycle is how regular you are how long your period lasts you should go on *****************.org they have a list signs of ovulation it tell you things you should look for to know when your ovulating and using ovulation kits that help to tell when your ovulating will also help and keeping track of your cycle but it could still take a while good luck
