I had mine done at 12 weeks.
I read loads about it and there are some horror stories on the net if you look. I spent hours looking for stories and if you google swine flu jab and miscarriage you will find references to all sorts. In fact, all the sites tend to direct you to the same accounts, and it is a truism that unfortunately there are so many miscarriages out there that it is inevitable that some might occur coincidentally after having the jab.
I cried when I had it done. I really was in two minds. I felt horribly responsible for anything that might happen. Before I had it done I rang my MW and my doctor for reassurance. They didn't help me that much to be honest! But I decided to go ahead with it. My partner was very relieved I decided to have it.
When I got home I found a really useful thread on here actually, with lots of ladies saying they had had it done, and apart from the sore arm there were no ill effects. I wish I had found that thread before. It made me feel a lot better.
I am fine, and happy that I had it done. I had trouble sleeping on that arm for a few days as it did really hurt. I think it might have hurt more than it should because the nurse put the needle right into the centre of a scar from an old TB vaccination that had gone wrong when I was a child.
Apparently your baby is immune from swine flu for the first six months after birth if you get it done.
It is true that it hasn't been tested on pregnant women, but most vaccines aren't. It is not a live vaccine, so you do not get a mild form of the flu in order to gain immunity. It uses the same technique as the normal flu jab, which has not been shown to have any harmful affects on pregnant women.
The dangers of swine flu in pregnant women are high towards the end of the pregnancy because of the pressure on the lungs from the size of the baby.
Hope this helps xx
