It depends on how long your cycle is. They say if you have a 28 day cycle you'll usually ovulate on the 14th day of your cycle. For example: If you have your period on the 27th of June and it ends on the 2nd of July, you would ovulate on the 11th of July. But, I have also heard that is a myth and women almost never ovulate on the 14th day and usually ovulate on the 5th-7th day. It is very possible to get pregnant a week after your period. With my first child, my period stopped on August 28th and I got pregnant on September 4th of 2009. I Hope this helps.
