Yes, you are looking at a third offense. In addition, with two OWI's so close together, you are likely to be ordered in for assessment by the DOT prior to conviction, under penalty of license withdrawal. Any suspension or revocation entered in the first case will serve as an unrelated prior year suspension, rendering you ineligible for an occupational for the duration of any subsequent revocation, yet you will still be subject to IID requirements even though you won't be able lawfully drive, and failure to comply with those could serve to deprive you of huber privileges. This is absolutely not something you can handle yourself. Get a lawyer, who can help mitigate the damage and plan for any unavoidable consequences. Get AODA & mental health assessments, and commence all recommended treatment. A fourth offense within five years of your third would be felony, carrying a possible prison sentence, so now is the time to address your problem, before the system addresses it for you in an unpleasant fashion. You can't afford not to.

If you are convicted of one of the pending cases, then the other one becomes a third offense. On a second offense, there is a fine, a DL revocation, and jail from five days to six months. The jail on a third offense is from thirty days to a year. You definitely need a lawyer. There are ways to defend OWI charges.

You have a child who is counting on you to be around and help this little person grow up. You are close to completing a very valuable educational program. Don't give up.
Part of doing the most you can to be there for your child is making sure you don't get behind the wheel when you have had ANYTHING to drink. Be aware that the legal limit on alcohol goes down for anyone with 3 prior drunk driving related convictions to 0.02 (that is one 12-oz beer or one 1-oz shot of hard liquor). Being in jail does not help your child grow up right. But more importantly, drinking and driving is extremely dangerous and is the cause of more than half of traffic fatalities.
Character is not determined by how many times we get knocked down in life. Character is determined by how many times we get back up, and what we do with ourselves once we are up. Don't make the same mistake again. If you can't do this for yourself, do this for your child. Promise that child that you will never do this again for any reason. Good luck. There are many places available that can help. Use them.
