Anyone have anything similar to my situation?!

Question. I'm currently breastfeeding a 38 week and 6 day old baby. Didn't go on birth control due to my past it messed me up. I haven't had a period at all since I had my daughter. Barely got it in September but now I haven't got it again. Wondering if I can be pregnant. Haven't taken a test yet. Waiting till the month is over to take one. Just too be sure. My bf and I had unprotected sex beginning of this month that's why.
