Generally, signs of early pregnancy are more subtle. Hormones due to pregnancy may start to take effect from about 10 days from conception, and the symptoms tend to become more intensified as the level of hormones gradually increase.
There are early detection pregnancy tests available that can confirm pregnancy as early as 6 - 8 days after conception has occurred (well before a missed period). Early pregnancy symptoms can sometimes happen before a missed period and before a positive pregnancy test. Especially the 3, 4, 5, and 6 weeks pregnant signs. Early pregnancy symptoms and signs are usually related to the pregnancy hormone hCG or Human Chorionic Gonadotropin which is responsible for pregnancy signs.
