What is my best option?

A lawyer would be the better options and they may be able to avoid points being put on your TDL.

My boyfriend of 21 got me pregnant at 16, only one week into the pregnancy I turned 17, We're worried that CPS may get involved

Quit posting . You are 17 now and I doubt anyone will ask questions,

Can I legally have a relationship with someone when I am 18 years and she is 16 years with parental consent?

If nothing sexual happens you are ok. It is better to wait and date her when she turns 17.

Can I go out of the country if I'm in probation

You need to review your conditions of probation. If they restrict you to Harris county you can ask the probation officer for permission to travel,

Yes, he can adopt you as an adult as set forth in Texas Family Code Chapter 162, Adoption of an Adult. Retain a family lawyer .

Will they actively pursue a warrant out for probation violation, also how long does it take for the warrant to be issued ?

Paying a fee late is one thing but testing dirty may result in a Motion to revoke,

Will I get jail time if I have prior felony convictions?

If you are convicted you will go straight to jail,

Can my ex boyfriends parents make me, a minor, have a baby I want to abort?

I agree with Ms. Holton . The sooner you go to plan parenting the better.

In 1990 I was charged with sexual assault of a child. I was given 7 years deferred adjudication,in which I completed.

You have to register as a sex offender even if you are given deferred . You can never expunge this case.

Can I get my probation dismissed bifore the 6 months

If you have completed all terms of probation retain a lawyer and file a Motion to early terminate, It is up to the judge .
