If you're like most women, morning sickness won't hit until about a month after conception. (A lucky few escape it altogether.) But some women do start to feel queasy a bit earlier. And not just in the morning, either — pregnancy-related nausea and vomiting can be a problem morning, noon, or night.
About half of women with nausea feel complete relief by the beginning of the second trimester. For most others it takes another month or so for the queasiness to ease up.
