could I be pregnant

Tedra

So I had my daughter 9/9/17 and my bf and I ended up having sex before my 6weeks was up. I have periods but they are all over the place and are not very consistent. Could I be pregnant even tho I still have periods? Also I sometimes feel flutters like I did at the beginning of my pregnancy but a friend of mine said ahe felt them too for at least a year after giving birth.
