please help

Okay so I believe like two weeks ago my boyfriend and I had unprotected sex but he pulled out. I have also been on birth control for two almost three months now but the first month I wasn't very consistent taking my pill. So my boyfriend pulled out but he did cum before that so I am worried that there might have been cum in his pre cum and maybe my pre cam in me. I'm so scared that me being inconsistent taking my pill might mean I'm preganant and I'm only 16. I have been nauseous all the time like I don't even remember when I wasn't but that's the only symptom. I'm supposed to start my period soon but I'm freaking out. And with trump being president don't we have to pay for abortions now? How am I supposed to find the money for that. If pregnant I would have to get an abortion. My parents are way to strict and I couldn't have a baby at this age. Please help. What do you think?😥
