People on Depo seem to either bleed alot, or not bleed at all. Its pretty normal that you have had no period in months.
Depo will not affect your preg test. Preg tests measure bHCG in your blood. Depo-provera contains progesterone.
Depo can give you PMS type symptoms, which can often be similar to early preg.
If you are still concerned, go to your doc and get a bHCG blood test done. The blood test is very accurate.
I havent had my period for about 5 months now...my doctor just said that it is usual for people that are taking depo..
if you think you may be pregnant, how far along would you be? usually tests are very acurate and if its negative, the majority of times..its negative. do you WANT to be pregnant? if so, your body and mind can "work wonders" and you may get symptoms of pregnancy even if you are not. also, many pregnancy signs are either your period coming or attributed to other things.. stress and so on. you said yo no longer have a period? when was the last time and has your dr. explained why?
