Hello, I am 8 days delayed. I was expecting my period on july 27 - July 31. Last month, i have experienced continous sickness within a week like diarhea, head ache, lower body numbness/unexplainable pain (from hips down), back pain for 2 days. I am confuse. I was not able to take my regular supliments for my hormone, & some vitamins last month. I took some synthetic meds to bear the pain which is new to my system. Coz I dont take these usually as much as possible. Can it be a reason why I got delayed? I am feeling weary & stress now. In addition, I am sexually active & had unprotected intercourse on the 7th day after my period. (Period:june 27, July 3: intercourse). i actually dont want a baby. Can pregnancy occur? :-(
