Pregnant?! Free insurance?!

I'm 18 and my boyfriend of over a year is 21. We had sex 3 times yesterday... Raw. He pulled out but I'm not sure if he got any pre-cum on me. I just started using this app and it said something about 3-10% chance of fertility yesterday and I should be getting my period on the 22nd of June. This isn't the first time we've gone through this. We typically always use a condom or I have taken a Plan B. What do I do? I don't have health insurance. Or a job currently . Is there a way to get insurance through Planned Parenthood for free?
