What Happens at 4 Months of Pregnancy? 16 Weeks Pregnant.

First day of last period
Most pregnancies last around 40 weeks (or 38 weeks from conception), so typically the best way to estimate your due date is to count 40 weeks, or 280 days, from the first day of your last menstrual period (LMP).
Pregnancy is counted as 40 weeks, starting from the first day of the mother's last menstrual period. Your estimated date to birth is only to give you a guide.
We can easily count the number of weeks in a month by first counting the number of days in the month. Then, we divide the number of days by 7 since 1 week has 7 days. For example, the month of January has 31 days, so the number of weeks in January would be: 31/7 = 4 weeks + 3 days.
The average calendar month is 4-5 weeks, but a pregnancy month is always exactly 4 weeks.
Four weeks isn't “just” 4 weeks—it's just about the 1-month birthday!
At 13 weeks pregnant, you're three months pregnant, although doctors track pregnancy by week, not month. This is the last week of the first trimester.
There are a few different ways the weeks of pregnancy are grouped into months, so this fifth month could range from week 17 or 18 up to week 20, 21, or 22.

Some women can feel their baby move as early as 15 weeks, while others don't notice it until closer to 20 to 22 weeks. It varies for each person and depends on a number of factors. There's no difference in the health of a baby whose movements are felt sooner rather than later.

Of course, some months have slightly more than four weeks.
4-Month-Old Baby Development
At 4 months old, your baby has likely doubled their birth weight. Babies this age typically gain about 1 to 1¼ pounds and grow about 0.5 inches per month. Your baby's developing vision allows them to track objects, and their increased neck strength helps them hold their head steady.
their skin is reddish in color, wrinkled, and veins are visible through the baby's translucent skin. Baby's finger and toe prints are visible. The eyelids begin to part and the eyes open. Your baby may respond to sounds by moving or increasing the pulse, and you may notice jerking motions if baby hiccups.
