Think i might be pregnant... comment!

Sooo my boyfriend and i have regular unprotected sex. Ik.. not smart. And we have been fine for 7months.. but recently i have had white clumpy discharge, headache, nausea, and pain under my arm. I took a pregnancy test. It was negative but i think i took it too early. Im not due for my period for 7 more days. So if im late i guess ill take another test. Im really scared... please comment.! Could i still be pregnant even if the test negative??
