Do you think I should retest?

Ok so, to make a long story short i started having what seemed like pregnancy symptoms in the beginning of january, mid Jan i took two HPT came back negative. Beginning of February i had a very abnormal period, i dont really consider it a period becasue it was mostly light to moderate spotting even though i was cramping a bit. i took two HPT tests after the spotting stopped and both were negative, i was still haivng symptoms, now some of the symptoms have mellowed out a bit but my period is a couple days late. I know stressing out can delay a period, but mine is like clock work no matter what is going on and i dont feel like i normally do before i get it and i have heard stories of people having bleeding while they are pregnant and not getting a positive HPT until months later which concerns me because not knowing for months could casue some damage(my mother has had a miscarriage before, and a child with Anencephally which adds to my concern about not knowing). Do you guys think i should retest or go to the doctor or wait awhile longer before i start thiking along that route? i know you all arent doctors but i just wanted your opinions to ease my worries a bit or point me in the right direction of what i should do at this point. Thanks
