So, though my question may seem really ignorant and misinformed. What contraception is best to use that will not cause so much affects? And if I was to stop it will everything go back to normal and will be able to normally conceive?
The best solution for your age and situation would be the female birth control pill. If you only plan to use them for a few years, the side effects should be minimal and you should be able to resume your normal fertility just after you stop taking them.
Condoms are too problematic due to the temptations to explore what it feels like without using one.
An IUD can cause very heavy bleeding, and may be a little traumatic to have it inserted and/or removed.
The timing method, while OK, can be unpredictable because the female cycle can be altered by stress. And if you are just getting married and moving in together, there is going to be stress as the two of you adjust to a new life that is shared.
Coitus Interuptus can work also, but can be too difficult unless the male has extraordinary control. If you are a virgin, there has been NO opportunity to practice this level of control, and besides most couples want to climax while together.
Hopefully there will be more options for birth control in the future that are not so hormone dependent. But for now scientists say that it is medically easier to stop just one egg each month than it is to try and stop millions and millions of sperm a day (the average male produces 85 million sperm a day per testicle).
