I want to but do I??

Hi, so to add some context first. Ive been with my boyfriend for over a year and I've fallen in love with him. We're thinking about getting married   And I definitely want to spend the rest of my life him. 
A few weeks ago I thought I was pregnant and was super excited but terrified at the same time. I was over a week late but we were struggling to get an appointment to confirm it. We were talking about it constantly and we'd made a lot of plan. Unfortunately I was not. And I was devastated afterwards. 
Then my boyfriend suggested we try again this time on purpose. 
I have anxiety and am extremely indecisive. I see everything that could possibly go wrong and everything that seems impossible to others. 
I'm planning on going to university in the next few years. And want to travel. He's older and is not planning on uni but wants to travel with me and the little one. I really want to and it's really important to him but I don't have a lot of experience with parenting. So I'm asking for some advice please??
