What to do if my gf gets pregnant f(22) m(22)?

So we had unprotected sex after 7 days of her periods. And this time her periods date is coming near like 1 week. But she isn't getting usual symptoms that happens before periods like pain in breast or joint pain. I am worried that she might be pregnant and if it happens we are fucked. So can anyone suggest how we should approach this and what if it actually happens then what are the precautions we should take to abort it. Plzz everyone guide me on this
