Sorry to hear you are not sure what you want to do yet.
I think most adoption agency's like you to be fully stopped all treatments for ttc for 6 months at least, but I might be wrong please check and don't just take my word for it.
For me trying to get excepted for fostering was quite stressful, unsure whether or not to get excited about it all or not,
We did have a few courses to go on, we had a six week training course that was called skills to foster, where we learned what sorts of children come into care and what skills were needed to become good foster carers, it was quite fun and not as scary as we thought it would be.
My older children had to go on a children to foster course which was only one day, they all enjoyed it, and learnt a lot from it, two of my children were to young to go on the course so we have just tryed to talk to them about what fostering entails.
We had a social worker come to our house and help us fill in our assessment of us, which she came around roughly every week for at least 10 visits for over 2 hours each time.
You are doing a good thing just even thinking about adopting there is so many babies and children out there who need a loving home.
Please see all the good in adopting, and it is a positive step forwards if you are ready for that next step, but if you don't feel ready, take your time think things through.
What age children or babies are you hoping to adopt?
And I hope someone else can offer you more advice than I have, as I know adopting isn't the same as fostering.
Take care speak soon x
