I was suppost start my period on Nov 17, I did not and i have took a pregnancy test and is was negative. I had all the signs that i was going to start my period but i didn't! What should i do? should i go to the doctor? or just wait to see if i start? what are my chances of being pregnant? I have not had any signs of being pregnant the only things is i do get dizzy every now and then, and that started on Nov 5.
