Hi I am a 19 year old female. I live with my fiance and we are sexually active. The sex is unprotected. I recently (about a week ago) had my period and seemed normal, but even before I had my period, I was constipated, and lately i m tired very tired, my lower back is sore, and I am having pains in my stomach, on both right and left sides, and some in the middle, I feel bloated, almost like I am going to start my period again, I do have some headaches but not nothing serious. I have not taken a pregnancy test. So I am just wondering if you think it is worth taking one or not. Thank you! LeAndra
