  • Recognize nesting instincts as a natural energy burst in late pregnancy that drives you to prepare your baby's space and home environment.
  • Monitor vaginal discharge changes - milky white is normal, but thick jelly-like discharge may signal your mucus plug is releasing.
  • Contact your doctor immediately if you experience very thin, liquid discharge as this may indicate your water has broken.
  • Expect increased discomfort from hemorrhoids and joint pain due to hormonal changes and extra weight in late pregnancy.
  • Understand that losing your mucus plug doesn't mean immediate labor - contractions may still be days away.

A due date calculator estimates your baby's arrival based on your last menstrual period or conception date. As you approach your due date, watch for nesting instincts, discharge changes, and other late pregnancy signs that indicate labor may be approaching soon.

The nesting instinct

At this point, you may find yourself experiencing a new level of energy, which can fuel a strong desire to prep the nursery, assemble cabinets and wash the floors. It is known as nesting, and it describes an expectant mother’s instinct to prepare a space for her newborn [1, 2].

With this new burst of energy, sex can be a great way to relax and relieve stress [1]. In the days before birth, your back and abdomen may feel sore. With the softening of the ligaments caused by the hormone relaxin, joints become more flexible, which can cause discomfort [2].

In late pregnancy, women may experience hemorrhoids. The causes behind this are the extra weight your pelvic area is supporting, and the expansion of veins due to hormones. Hemorrhoids are accompanied by pain and a burning sensation, both of which can be exacerbated by bowel movements. Make sure to use moist flushable wipes or wet toilet paper after evacuating.

Tell your doctor if you experience hemorrhoids, especially if they hurt and bleed. To relieve severe inflammation, your doctor may prescribe medication [3].

If you are expecting twins

Don't worry if one or both babies are taken to the nursery for observation after delivery. This is not uncommon with twins, especially if there’s a significant weight difference between them. Carrying twins for more than 38 weeks is considered a risk factor in itself, so for them to be under the care of a neonatologist for a while is best [4]. This also gives you a chance to rest, which will soon be increasingly difficult!

Discharge

In the last weeks of pregnancy, you will experience additional vaginal discharge. It should be milky white, with no foul odor. A thicker, jelly-like discharge that is white, pink, or brownish is a sign that the cervix is ​​softening and that the mucus plug is being released, up to this point its job has been to shield the cervix. Losing the mucus plug does not mean that labor will start straight away, it may take several days before contractions begin. On the other hand, some women will not lose the mucus plug until labor starts [5].

A very thin, liquid discharge is a reason to call your doctor immediately because it may mean your water broke. Seek immediate medical assistance if you notice bloody discharge [5, 6].
