Week 12 of Pregnancy: Dizzy Spells
During pregnancy, progesterone increases the flow of blood to your baby, resulting in lower blood pressure and reduced blood flow to your brain — giving you that dizzy feeling all over.
As you near the end of your first trimester, your uterus, now about the size of a large grapefruit, begins to migrate from the bottom of your pelvis to a front-and-center position in your abdomen. If you're lucky, this will bring an end to one pesky early pregnancy symptom — the constant urge to urinate. Also slated to diminish somewhat now that you're on the cusp of your second trimester are some of those other early pregnancy symptoms: nausea, super-tender breasts and nipples, food aversions, fatigue. But don't look now (though — considering the symptom — maybe you should), there's a new one added to the mix: dizziness.
