Hi! I'm 17 years old I've oh been on the depo for almost 3 months I get my next shot soon. I got my first shot on Oct. 30th & I didn't get my period in Nov. But I got my period in the beginning of Dec. My boyfriend & I had sex on Jan. 3th. I'm freaking out because my friends had told me that it's possible to get pregnant on the shot but my doctor told me it's really effective? But day after we had sex I started spotting a little bit so I really don't knw what to do or think right now I need help ):
