17 and possibly pregnant...

So my boyfriend and I rarely use condoms 
I have two period tracking apps and one (p.  tracker ) and this app the p.tracker the one I've been using like a few weeks longer says I'm 6 days late but <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says not until this weekend. We've been having sex atleast once to twice a week one to two times each time depending on how much we see each other. I do not take birth control either/
 I'm just so scared.someone please help?!
I might have to run away and not tell my parents anything... they'd be so upset. My dad is a baptist church pastor so they are both religious and are big on saving your virginity. 
 And they'd be so very hurt and mad. Idk what I'm going to do if I am pregnant. I am NOT getting an abortion. That is something that will never happen. It was my decision to have sex, so  I have to take what possibilitys that come with that.
