I Had An Appointment At The Clinic March 13 2013 For A Pregnancy Test . They Took My Urine And My Blood Work And Did Some Work On It To See If I Was Pregnant! Its Turns Out Negative . My Period Was Due 3-5-13 It Is Now 3-26-13 Witch Means My Period Is Already About 21 Days Late ! Now I Must Say My Boyfriend And I Had Unprotected Sex On March 14,15 And The 17 Witch Was My High Fertile Days And On The 20th Witch Was A Day After My Ovulation Day . A Few Days I Should Say After That My Breast Have Became Really Tender And Heavy . On The 23 Of This Month I Started Throwing Up Around 10:00 pm . On The 24,25 And Today I Have Some Diarrhea . For The Past Few Days I Been Having Mild Abdomen Cramps , Tender Breast , Nausea , Increased Cervical Fluid . Can I Be Pregnant ? If No Is There Another Reason Why My Period Is This Late ?
