Also here is an article on implantation bleeding.....
After ovulation the egg travels into the uterus and burrows into the lining of the uterus. For some women implantation will cause slight bleeding or spotting. This is called implantation bleeding. This is sometimes confused for an early period.
What does implantation bleeding or spotting look like?
Implantation bleeding, also called implantation spotting, does not look like a regular menstrual period. Implantation bleeding is scanty and usually pink or brownish discharge.
Implantation bleeding or menstrual period?
Implantation bleeding normally occurs a week to a few days before your period would normally start. Spotting that occurs around a week after ovulation is likely implantation bleeding; whereas, spotting that occurs very close to the time that your period would normally start may not be. A normal menstrual cycle generally starts off light and then gets heavier. Spotting can sometimes be the sign of an early period. If this is the case, the spotting will pick up to heavier bleeding. If you have spotting right around the time your period would normally start, it can be more confusing. You will need to take the wait and see approach or take a pregnancy test to determine pregnancy.
What if I feel like my period is about to start?
If you have had spotting and think it might be implantation bleeding you may be paying very close attention to your body. If you are trying to get pregnant, the good news is that early pregnancy symptoms feel very similar to the start of your period. If you are pregnant you may begin to notice symptoms of early pregnancy right around the time your period would normally start and sometimes sooner than that. If you suspect pregnancy you can test for pregnancy as early as ten days after ovulation.
How common is implantation bleeding?
Implantation bleeding is fairly common with pregnancy. Twenty to thirty percent of women will have spotting during early pregnancy. If you have some light spotting before your period would normally start this is not something to worry about and may be a sign of pregnancy.
