<s>[INST] Ive been on the Depo shot for a year me and my boyfriend has had unprotected sex and he has came inside of me...every morning that I have got up Ive had a brown discharge but it only occurs in the morning....Im also having lower back pain....stomach cramps.... by the way I dont have a period at all anymore because of the depo shot...could I be pregnant? [/INST] Hi, Thanks for the query. As you are on demo shot, the possibility of pregnancy is less. The possible causes for your spotting are :- Side effects of the demo shot. It can cause intermenstrual spotting, break through bleeding as side effects. -Pelvic inflammatory disease. Chronic pelvic inflammation can present with cervical erosion. And that can lead to spotting, pain abdomen etc. - Post coital tear. Can present with spotting and pain. So, better to consult gynecologist once and get examined. By examination causes like post-coital tear, cervical erosion can be ruled out. If your doctor recommends go for ultrasound. Ultrasound will help in ruling out the possibility of pregnancy and also any endometrial abnormality. Then with your doctors' advice you can go for additional dose of hormones to control the spotting. Take care. </s>
