When does your body detect your pregnancy?

How long has it been since the incident occured? The HCG hormone (pregnancy hormone) starts at the time of conception, but actual levels may take 2 to 3 weeks to show positive on a test. A woman's body also begins to prepare for the growth and development of the fetus at the time of conception. You should call a planned parenthood hotline # in your area to help you with this. If you are pregnant and want this baby...good luck. If you are unsure, it could be stress making you feel this way. If you are not pregnant and trying to be...good luck with that too. God Bless!
