Nearly everyone has such sound advice to offer to you, there isn't much I can add.
In lieu of offering you my opinion on what you should do, I can ask you to think on a few simple questions.
1. Are you willing to let any of your future children die rather than take a blood transfusion? If you are, and in the future the organization reverses their position on the blood doctrine due to the emergence of 'new light' (their buzzword for doctrine changes), are you willing to accept that the change was divine direction from God himself and not be resentful that your child died under the 'old understanding'?
2. Are you willing to stop celebrating all regular holidays (No Christmas, no birthdays, no easter, no halloween, no thanksgiving, no national holidays, no mothers/fathers day, etc), and to give up celebrating any form of those days with your 'normal' family?
3. Are you willing to take as truth any mandate handed down in the publications of the Watchtower Bible and Tract Society and follow them without question, knowing that keeping all of your new friends is conditional upon your acceptance of all the doctrine? Are you willing to believe that anything said by the Watchtower is looked upon as direct communication from Jesus Christ to his people here on earth?
4. Are you willing to voluntarily enter into a contract with an organization (your baptismal vows will require you to pledge your allegiance to the society as God's sole channel of communication on earth)? Are you then also willing to, if at any point in the future you begin to question their teachings, break that contract and be shunned by all your 'christian brothers and sisters'?
5. Are you willing to ignore that little voice inside of you that led you to post the question that started this thread? Are you willing to ignore all the negative information you've found regarding Jehovah's Witnesses as the voice of Satan attempting to deter you from the 'truth'?
If you can answer an honest 'Yes' to each and every one of these questions then I suggest you begin that bible study right away and work toward baptism.
If any of these same questions give you pause, continue your search for information, and listen to the instinct that guided you to research the matter in the first place. Once you are a witness, you will be forbidden to engage in "independent thinking" so take this time to do as much of it as you can before making any decisions.
I wish you the very best, and hope that you follow the path that is right for you.
