It’s no surprise that doctors don’t always think to get pregnant again.
But it’s also no surprise to find out that if you’re pregnant again, you might have a different baby in the future.
And there are some surprises too.
Pregnant women often go through periods when they don’t get pregnant.
The baby doesn’t go to term.
They might not go into labour.
They don’t even have a birth.
It’s a time of uncertainty, and that can be really scary.
And if you do have a baby, it can feel really hard to say goodbye.

A special thanks to the staff of the hospital where I gave birth.
They were really helpful.
And to the people who have helped us.
Pregnancy is a scary, emotional experience, but it’s a good thing that you’re having it.
You’re probably thinking: what’s going to happen?
And the answer is: it’s okay.
It means you’re not alone in this strange new world, and you’re safe.
You’ve had a child, and this baby is going to be fine.
You have the support of your family and friends.
You know how important it is to stay positive and optimistic about everything.
So what’s the problem?
What happens if I don’t have a pregnancy?
And is it really possible to go back to being a single mother?
Let’s start with the facts.
What is pregnancy?
Pregnancy means two things: a time when you’re trying to get your eggs into the right place, and a time in which you can have a child.
The eggs are about two weeks old at the time you ovulate.
They’re called gametes, and they have about four to five cells each.
The egg is then fertilised by a sperm cell, which is carried into the uterus and fertilises an egg.
The fertilised egg is called a zygote.
When you ovate, the eggs have a blastocyst – an embryo – and this blastocyste is about three to four weeks old.
You ovulate again during this time, which makes the cycle repeated, so that the cycle continues every two weeks.
But when you don’t ovulate, your eggs do not have any cells to fertilise them.
It doesn’t matter how long you’ve been pregnant, you’ll still have a small number of eggs.
And they’ll all be fertilised in a few days, so you’ll have two to three weeks’ worth of embryos.
The next thing is the pregnancy itself.
Your body does all sorts of things during pregnancy.
Your uterus starts pumping milk to your breasts.
And you have a continuous flow of blood through your legs and the thighs.
But the next step is to have a fertilised zygode.
You get a fertilisation at the same time that you ovulating.
The zygodes start dividing in the uterus, and then you have another fertilisation, and so on.
The end of the cycle is called the “ovulatory cycle”.
You can think of it like a big dance floor, and it happens very quickly.
At the beginning of your cycle, you have about 10,000 eggs.
Each of them has about three cells each, so they can divide to produce a zombified egg, which has three cells.
The last cell is the fertilised embryo, which also has two cells.
It becomes a baby at about a week old.
But you’re still not sure how to make the baby.
How are you going to get it back to a normal size?
How will you hold it?
There’s a lot of mum advice.
“Don’t eat it”, “do not let it eat you”, “make it stay in the fridge”, “don’t let it grow”.
Some women say that they don.
They do, however, think it’s OK to take the egg, and eat it, and watch it grow.
It goes back to the mother and they make a baby from it.
And so on, and on.
In the first month or so, you’re getting a little bit of extra nutrients and vitamins and proteins.
Your muscles are getting used to the extra weight.
The first week is when your egg starts to implant in your womb.
Then you’re able to get some blood flowing into the womb, and the embryo starts to form.
It starts growing, and within about a month it can start to feel a little bigger.
It has a head, it
