Hi hun!
It can be scary at first but after your first few jabs then it will be a lot easier. I think the mental stress is worse personally, the medication is fine actually.
With my first IVF we got a BFP and i thought "this is quite easy!"
then at the 20 week scan the baby was diagnosed with fluid on the brain, nothing could be done to save her from severe brain damage so we had to terminate at 24 weeks.... Horrific. I was not allowed to start treatment again until 5 months later when we had a frozen embryo transfer with two blasts - failed. IVF #2 was cancelled due to understimulation and dropped down to IUI which failed. IVF #2 (again as i call it) stimmed better, 2 embies transfered - failed. We had one frozen embie out of it and thawed that but it arrested so they were unable to transfer and it failed again. We are now in the process of IVF #3. Its a bit of a lottery and you never know what could happen. The important thing to remember is that with IVF you have basically a 1 in 4 chance of it working so 25% chance BUT people are in that 25% and it can work first time, others are not so fortunate and it can take many tries and to be realistic, sometimes it never does work for people. What I have learnt though is that it doesnt matter if you get 20 eggs or 2 eggs, it doesnt increase your chances it just increases your chances of trying (more times) Also with transfers some people opt for a 3 day and some a 5 day. There is no scientific proof that one works better than the other although each hospital has its owns belief!
I hope this helps and that you are one of the very lucky ones and it works first time but to reassure you, I have had som many procedures now it just feels like a way of life!
Good luck xxxx
