just wanted to know

Trinity • SAHM ~ 31 ~ Mum of 1 🌸🤍
So, I had my daughter in September. I went on the injection (contraception injection) on my 6 week check. I haven't been for another since as I bleed for another 5 weeks whilst on it. 
This was a while ago now and I still haven't had a period. There is no chance I could get prehnant again is there? Whilst not having a period.
