I experienced teenage pregnancy which means I was pregnant before I turned twenty.
Was that a positive or negative experience for you, beyond your child them self?
It was positive for me but I did have some of the same problems as other women.
Was the father a part of the experience?
He was not, we were not married and there was a social stigma attached to the pregnancy.
I understand completely.  My ex wife was 19 when she got pregnant and we married.  I was a little older but it was tough on her for sure
There are so many social issues associated with teenage pregnancy such as negative outcomes in life. I haven't experienced them though.
Well that is good, consider yourself lucky.  Hope everything worked out for you in the end.  
It did, I wouldn't change anything. How was your ex-wife?
When she got into her thirties she started having some regrets with missed opportunities to experience life in her younger years.
