What are the chances ?

What are the chances of me being pregnant? I have been on the 2 month birth control injections since I had my son (got first one in hospital), I had 7 weeks of pp bleeding and at around 3 month pp I started my period while breastfeeding, had a period each month even while on the injection and my last period was at 8 months pp and my son is now 10 months. I was on the same injection for 7 years before we decided to have a kid and still had a period every second month just before I had to go for the injection.. I am planning on taking a test but I am scared.. I didn’t have any symptoms until 4 months into my pregnancy I didn’t know I was pregnant till almost 3 months. What do you ladies think ?
