Hi Nat, Congratulations. You seem like very sensible well together person you are definitely not too young to be pregnant at 22. I had my first child at 20, I was 19 when I found out I was expecting him and it was very big shock. But myself and partner had been together for 4 years already and were living together so it was the next step in our relationship. I had my next son at the age of 23 I had 2 miscarriages in between the first 2, losing twins when my eldest son was only 6 months old and another on September 11th when the world went into chaos with the twin tower bombings.
I had my 3rd son when I was 25, and when he was 6 months old I lost another baby. None of my pregnancies were planned and all were shocks as I was taking contraception, and in the beginning before I had the boys they told me I could not have children because of PCOS, but then find out I am overly fertile! But I would never change having my sons, Yes I was young but they have the advantage of having a young mum full of energy and when they are grown up I will still be quite young myself.
My family is complete now and I have taken the steps to make sure I don't get caught out again and I am waiting to be sterilised but as I'm only 27 they say it is too young.
Having a baby no matter what age you are is a wonderful experience it can be hard but that is part of the package, just wait until you are holding that little miracle in your arms you will feel so wonderful nothing can beat that first moment.
I wish you and your partner all the best.
