No, your GF will not be pregnant, from the facts you have given me, above.
I realise that this is an old post, but I'm answering it in case anyone else finds it helpful.
You are covered by Depo for 12 weeks, regardless of any bleeding you may experience in between shots.
You do not have periods on Depo. A period is flushing out the lining of your womb, including an unfertilised egg.
You do not produce an egg when on Depo. What you can experience is break-through hormonal bleeding. This can last until you have your 3rd Depo shot. By then, it usually has stopped altogether.
You may get hormonal symptoms on Depo, such as bleeding, bleeding after sex, pregnancy like symptoms (because Depo tricks your body into thinking you're pregnant, to prevent you releasing eggs each month), such as bloating, sort breasts, lower back ache (Depo softens the ligaments in your back, as if preparing it to expand to make room for a growing baby), mood swings etc. Most of these symptoms pass as you get your next couple of shots.
As your GF has found, sometimes you do experience hormonal symptoms over continuous use of Depo. Unfortunately there are no forms of hormonal contraception that guarantee no side effects. It's just a case of finding the best method for each individual.
If you choose to come off Depo, you may well find you get these same hormonal symptoms for months, whilst your body readjusts. It can take up to 18 months to regain your fertility.
Hope that helps.
