Gearing up is the mantra of the pregnancy week thirteen under second trimester week-by-week pregnancy calendar.

As for the physical changes that body undergoes in week 13th, the breasts continue to change. There is a tendency to wear less fitted clothes as the pregnancy progresses. Uterus too is expanding as informed earlier and a painful sensation in the abdomen area could now accompany. Round ligament pain is the technical term to explain the mentioned stretching of the uterus and the corresponding abdomen pains. Simply relaxing can cure the pains however if they stay for longer durations and are complemented with other issues like bleeding or vomiting, get an appointment with the doctor at the earliest.
As for the regular prenatal development check, the doctor would keep an eye for the blood pressure count, weight, fundal height (uterus growth), baby's heart tones and urine.
Pregnancy pillows are a certain way to beat the un-welcomed pregnancy pains and steal some hours to relax easily. The increased uterus size, along with other complimentary factors like stress or discomfort of carrying a baby makes it tougher, as time progresses, to rest easily. Pregnancy pillow then can provide the desired comfort with ease.
