I got my depo shot a month after my last period on June 11th . Waited two weeks after to have sex on June 28th . A week later I experienced brown/black discharge then came on my period. Monday July 13th I experienced back pain and was experiencing dizziness and had pink , thick , clot like tissue come out of me . The day before I was nauseous Idk if I had a miscarriage or a chemical pregnancy . Can anyone give me an answer ?
