I took a pregnancy test 4 days before my missed period

Welll, I took a HPT today & my period is due on Thursday or Friday. So I figured it'd come out accurate. But it came out negative. But for the past week and a half, I've had lots of symptoms. Such as; feeling nauseous without vomiting, i had cramps for about two days but they didn't feel like normal period cramps they had a stabbing feeling on both sides of my lower abdomen, i had two small dots of pink blood on my underwear, a few headaches, peeing every hour while I'm awake and also eating double of what I use too, and I've been way more tired then usual I wake up at about 11 am, and get tired by 5 pm. It ruins my day! But ladies please help me & tell me if theres a chance I could be pregnant still. My family doesn't believe that I am since my test was negative. Such as my hubby

:'( PLEASE HELP MEE OUTT!
