I had my first and ONLY depo shot in may and was due to have it don't on the 14th August 2013 but I decided I didn't want to go as I would like my 2nd child and I have had sex with my boyfriend every night as we do . And I am now experiencing diariah / backache abdomanal pain and cramping . I am spotting and have vaginal discharge that is white and savere heartburn. I have not had a period since may as that's when the depo stopped it . Does anyone know if I could be pregnant or not ? As I think it would be to early for pregnant test .thanks
