Trying to find out if im pregnant?

i don't want to make myself look stupid by going to the doc's saying that i think i'm pregnant and i'm not i just never had the light period before and the signs that go with pregnancy are there i have 4 children but they say every pregnancy is different ive always known before as ive had the morning sickness and thats why im trying to find anyone who has ever been pregnant and never had morning sickness.im really confused as ive been preg 4 times before you'd think i'd know if i were,i will do another test would you recommend i use any one in paticular as my gp does not do this anymore they say its to costly thanks alot for listening kerry!
