Period help?

should i go to the dr or wait it out more ?

Ok so my period is 7 days late today. My cycles usually range from 32 to 34 days but as of now im on cycle day 42 i have never gone through this before my period is usually on time , or early or like 2 days late . i already took some pregnancy tests and took one this morning and its negative. I know sometimes its normal from what I've read if you've been on birth control or sudden weight gain or severe stress but i have none of that so im super confused . and now im getting stressed cause its not starting i want to be pregnant but im stressed now not going what's going on period not here but negative pregnancy tests ?
