Ok so im 17 and i got the depo shot on february, didnt go back for the second dose on may 7th so ive been brown spotting, cramping with no period, diharea, nausia & been feeling bloaded nd tired, my breasts are feeling heacier also... I took a at home pregnancy test nd it came out negative, so i went to the clinic where it also came out negative, my sister said that itll come out negative if your on early pregnancy so since it came out negative at the clinic i took another dose of the depo shot yesterday, thats where i messed up because it just made my symptoms worse so i was wondering if a blood test is more accurate than the stick ?
