I am now 8 days late for my period. I've been very regular the past 2 years. I have been a tad more stressed this month but I believe that the most stressed ive been is because of this missed period. I have had sex but there weren't any incidents where he finished In me. I took a pregnancy test on day 7 of my missed period and its negative. But I'm still extremely worried. Being 20 with strict parents I'm praying I won't be pregnant just yet. I'm taking more tests tomorrow. I'm wondering how many women have experienced this before??
