20 weeks pregnant with twins is a huge milestone. For one, you’re officially half way through your twin pregnancy journey. Well done!
But it’s not only that. You’ve either had or are going to have your mid pregnancy scan in the next week or so, and that could also mean that you’ve recently found out the sexes of your babies!
That’s huge! Now you know what you’re having, you can start to decide on names, get the nursery finalised, and start telling your friends and family.
We also seem to find that having the sex of your children confirmed makes the situation you’re in absolutely real, so if you feel a little bit overwhelmed this week, try and relax. It’s completely normal.

Your Twin Babies at 20 Weeks Pregnant
At this mark, your babies are around 10 ounces in weight, and they’re easily over 6 inches long. Picture holding a small banana cupped in your hand. That’s how big your babies are right now!
They’re also starting to develop their primary sexual characteristics. Boys will have a tiny little penis, and their testicles will have started descending, to find their eventual home between the legs. But first, he’ll have to finish growing a scrotum, because right now, they won’t have anywhere to go.
If you’re having girls instead, they’ll already have millions of eggs in their ovaries. Seven million, to be exact. By the time she’s born, she’ll only have two million, but that’s still far more than you could use in even a hundred lifetimes.
She’s also going to have a fully formed uterus by now, so you’ve got a uterus inside a uterus, which is some twinception going on. As well, her vaginal canal will have started its development this week.
Twin Pregnancy Symptoms at 20 Weeks
You should still be feeling pretty good right now. The symptoms you’ve got are relatively minor, you’ve probably got a lot of energy, and you should have recently found out how well your twins are doing. This tends to translate into you feeling great, so make sure you take advantage!
- Aches and cramps: Expect all these fun things to still be punishing you, so take it easy, stretch regularly, and treat yourself to little breaks every now and then.
- Swelling: You’ve probably already experienced some of this. Unless it changes, or it’s sudden, then relax. Swelling is a normal part of pregnancy.
- Digestive issues: Hormones and the extra space your babies are taking up can cause issues with your digestive system. Try and stay away from foods that you know cause you issues, especially if they’re spicy or high in sugar.
- Vaginal discharge: Your body is trying to keep your babies safe from bacteria and other problems, so don’t worry about extra vaginal discharge, unless it smells odd, or is a gross color like green or yellow.
- Lack of breath: You might have already felt this, but as your twins start to crowd out on space, there’s less room for your lungs to expand, so if you feel a little lightheaded, take it easy.

20 Weeks Ultrasound Twins
You should be having your mid pregnancy scan soon, if you haven’t already.
If you don’t already know, a mid pregnancy scan is a also called an anomaly scan, and the real purpose of it is to check the growth progress of your babies, and make sure that they’re developing properly in the womb.
Expect the scan to take around half an hour. You’re going to be able to see a lot more on this scan. Not because it’s using any more technology, but because your babies are bigger, and there’s a lot more that an ultrasound will pick up.
First off, you’re almost certain to hear heartbeats, and your sonographer should focus on your babies face and hands to make sure everything is fine, before moving on to looking at their internal organs.
If this is your first scan like this, and you’re trying to make sense of it, then you should be looking for whites and greys. Skin and organs will be varying shades of grey, and bones will be white. Everything else will appear black.
Make sure you talk to your sonographer and medical staff before the scan, to let them know where you stand on learning the sex of your babies. Some hospitals won’t tell you without asking, as a matter of course, but it’s good to check.
Things to Do This Week for a Healthy Pregnancy
- Check your diet for iron levels. As your blood volume goes up, it can sometimes be a struggle to produce enough hemoglobin for all the new red blood cells you need. So snack on a steak, or for the veggies amongst us, lentils, soy and spinach!
- Look into childbirth classes, especially if this is your first time. Talk to your partner about when you can both go, and make sure you make time. Knowing what you’re in for and the techniques they can teach you to relax really helps when you’re on the delivery table.
