Most times when you're pregnant you won't notice much if any Pregnancy Symptoms during the first three weeks that you're pregnant.
Pregnancy Symptoms don't usually begin to show up until after 3 weeks into the pregnancy and when the Pregnancy Symptoms do show up you'll have frequent urination, heightened sense of smell, nausea, tender breasts, fatigue and implantation spotting.
Implantation bleeding or spotting is when the fertilized egg implants into the lining of your uterus.
The implantation and other bleeding usually happens 9 days after ovulation and fertilization of the egg but for some woman the implantation spotting and bleeding can happen between 6 to 12 days after your ovulation happens.
