What are the earliest signs of pregnancy?

Ok so I just recently found out that you can get pregnant from seminal fluid. Now I'm freaking out! Me and fianc� didn't have actual intercourse but we grinded naked and there was some seminal fluid coming out. He would wipe it off before we grinded most of the time. Now I am scared to death I'm only 17 and I DON'T EVER want kids. I find nothing appealing about having kids. If I'm pregnant I don't know what I will do. I would want a abortion but idk if you need a parents to sign in MI. I don't want to carry a kid either not for many reasons. I don't want to ruin my body, I already have major health issues, I am afraid of dying during childbirth, and of course I can't afford it. So my questions are What are the earliest signs of pregnancy? Do you need a parent to sign in the state of MI to have a abortion? How much does a abortion cost at planned parent hood? Is the abortion pill safer? How much does the abortion pill cost? Is it for sure true you can get pregnant from seminal fluid? Also I don't know if I'm pregnant yet it hasn't been even two weeks after we did that but I am paranoid and don't judge me or give me religious reasons on why I shouldn't do this I am a christian so yeah. Pls I want serious answers pls. Thanks
