Hi i am also 21 in the same boat as most of you. My period is 5 days late, i had sex around the 10-12th of this months, started having cramps a couple of days ago but no period. I ovulate the 10th-15 of every month according to mymonthycycles.com, last month i had sex on the 10th and my period was 4 days late luckly it eventually came, but this month seem different, it feels as if its gonna come on any minute but when i go to check its not there. Last night i dreamed that i was pregnant and was so excited, but scared because i might not be. How long should i wait to test? Should i just wait it out to see if my period is gonna come on or go test?
