I have been feeling this way for probably a week or so now. I'm a 20 year old Female who is active and eats healthy. I drink plenty of fluids and am a little concerned if its either very early pregnancy symptoms or something else. My last period way March 5th of this month and I should be starting in 11 days. I sometimes feel as if I'm about to start my period and have blood gush out and also lower back pain. I went to the doctor today but all he did was give me bowel movement medicine. I have been pooping but sometimes its pellet like. I would appreciate any suggestions or comments!! Thank you so much!
