I have brown shiny discharge. Mild cramping, negative hpt. Had fatigue, vivid dreams, sore breasts, lower back pain for the past week. Pregnancy?

Pregnancy test. If you had unprotected sex since your last period and have missed a period, do a home pregnancy test. If it is negative repeat it in a week. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex.
