Possibly pregnant?

So I have a predicament. I am due to start my period in a day and a half. But I am staring to feel very sick, my stomach hurts in the evening and in the morning. My breasts hurt, and my back is absolutely killing me, along with a headache. I took a pregnancy test 2 days ago because I feel just off, and I just got married so my husband and I haven’t been real into using protection at all. The test was negative, but I’ve just never experienced period symptoms like these. So I’m wondering what y’all think. Should I take another one or am I just suffering from period symptoms?
