Pregnancy and The warmed-up effect
If you’ve been pregnant once before, you may notice that you’re bigger than you were at the same time during your last pregnancy. You may also notice that side effects seem to be happening earlier this time.
You could call this the “warmed-up” effect. Like a balloon that’s easier to blow up the second or third time around, your uterus may expand more quickly and easily once it has been through one pregnancy. Your abdominal muscles and ligaments have already been stretched once, so they give more easily as your uterus expands on the second go-round.
The downside is that because your uterus is getting bigger, faster, you may experience symptoms such as pelvic pressure and back pain sooner in this pregnancy than you did in your first pregnancy.
