Symptoms: Lower cramps , light vaginal bleeding , dark red gooey blood

Doctor: Depo shots are hormonal injections and may cause unscheduled spotting, which is, in fact, one of its commonest side-effe cts. Getting a home pregnancy test is a good idea to alleviate concerns on pregnancy. Please consult your healthcare provider for recommendations based on your specific circumstances
