Trying to conceive, need help?

It's not neccessary, your young and you should be fine (it's only when there's a history of fertility problems in the family that you should worry) Just get to know your cycles and when you ovulate and try around your fertile time and you should be on your way. It can take 6mths to a year for healthy couples to conceive so just enjoy your time together and try at the right time and it will happen when your body is ready. Good luck :)
