19 and Pregnant?

So, recently Ive been feeling a bit different, in an off kind of way. Getting symptoms here and there that im pregant, but im not even suppose to get my period for another 9 days. My Fiance and I aren't trying to get pregnant, because we can't financially afford a baby at the moment. Would it be too early to take a pregnancy test? We made love around the 15th and again on the 20th. Im afraid because of what both our parent's would say if I we were expecting.
