5 days until my missed period, im trying to conceive but had a negative HPT, could I still be pregnant?

Have been trying to conceive, i got my period the 16th of june and tracked my ovulation. I took a pregnancy test this morning, the one that says know 5 days before you missed period but it was negative. I havent had any PMS symptoms like usual except little twinges. Could i still be pregnant? is it too early to test still?? is there any other way besides a HPT that i can tell??
