<s>[INST] Hi I had a baby in march after I had him I went back on the depo-provera injection(this was my usual contraceptive before I decided to get pregnant and I didn't have any problems my periods stopped completely after my first injection). I had my first injection 2 weeks after his birth. I have been spotting ever since. I have now had 5 injections and it doesn't seem to be stopping. On my last injection 20-08-13 I was prescribed norethisterone. I have just started taking them but I am wondering if my body is not able to have the depo-provera contraceptive anymore? [/INST] Hello, I would be happy to help you with your question. Breakthrough bleeding on the depo shot is not uncommon.  It is definitely less common after you have been on it so long, though in some women there is thinning of the uterine lining that leads to this breakthrough bleeding.  It is appropriate to treat this with norethisterone, but I believe that you would also benefit from an ultrasound of the uterus and a discussion of other forms of birth control. I hope that this helps and good luck! </s>
