We had IVF at the end of 2006. DD has just had her 8th birthday.
We also had a FET three years later which failed.
My advice would be:
Make sure you are happy with your clinic
Go in with realistic expectations. Many many cycles fail. We were told to look at the first one as a trial to see how I reacted to the drugs. Then they could adapt for a future cycle.
Our miracle baby came from this cycle. (21 eggs, 18 to fertilise with ICSI, 15 fertilised, 7 made it to transfer day. 2 transfered...one baby. 5 frozen. All thawed for FET, 2 suitable to transfer...no baby)
I found the injections very painful.
They also gave me headaches, mood swings etc....
DO NOT go out and buy new jeans 2 days before egg collection. You will be rather swollen and much larger than normal...the jeans may then not fit three days later. (Or maybe that was just me.,....)
Make sure your DH/P is supportive. You could feel really quite hormonal.
If if does not work and they offer counselling then seriously consider taking it. I did not after our failed FET and 5 years later am still trying to come to terms with it.
Although some people have successful natural pregnancies after IVF this is not a given....although some people will try and convince you it is.
Good luck. It's a long road, and the Two week wait after transfer is the longest two weeks ever, but if you are lucky and it works it is worth every minute of it..
