Okay so I was due for my depo shot in September but I missed it. I had a cycle in October however i Had sex with my boyfriend a day before my cycle came on. Its now November and we've had unprotected sex again. Since I've been on depo I haven't had a regular cycle. So I wouldn't know if I've missed it or if its late . What are the chances of me getting pregnant (which I dont want another baby) right now ?
