OBGYNS SUCK WHEN TTC UNDER 20

So I would go to my OBGYN and tell him I wanted to get pregnant and he would help me and everything but he would always tell me you should wait and you're too young, asking me if that's really what I want and i should wait till I'm married.... So now I'm scared to go to a different obgyn because I feel like they are going to tell me the same thing and it just makes me uncomfortable. I want a baby right now and I'm ready for one financially and mentally. I love children. So does my S/O he wants a baby now too and we've been trying but I don't have a regular period and I ovulate late and we never get it... I've been TTC for about 3 years. So I know I'm going to need help from an obgyn I'm just nervous and I don't want to be... They make me feel embarrassed.....
