What Doctor?

Paige • Married to the love of my life!❤️ I have a beautiful 6 year old daughter, and a handsome 2 year old son! Currently pregnant with baby #3!🥰
I am 17 and I just found out I was pregnant. I haven't told my parents or my fiancé's parents either. I currently don't have insurance. I don't know where to star about getting insurance or even what Doctor to go to. I wanted to get blood test to confirm before we told anybody including parents but I have to have a parent because I'm underage. What do I do?
