Is this right?

So me and my boyfriend have decided to try for a baby when he gets his degree in two years. We are both 20 so we will be 22. Is this a good time? Because I've always wanted to be a mother I feel like I can't wait any longer I'm sick to death of people telling me to 'live my life' I've done ALOT in my years and I'm ready to settle down I don't care if I'm 20 or 45 like I said I've done a lot. I've been on a lot of vacations I work 2 jobs and have my own home. He works full time and he is a student.  He's becoming a sports therapist which is a good paying job and hopefully he can run his own business in the future. We are planning on getting engaged before we have a baby and marriage can come later in the future.
