pregnant? maybe

So I just gave birth to my son 9 weeks and 3 days ago and I started my period three weeks after and it's not time to start again and I'm six days late and having discharge and cramping like I did the first time I found out I was pregnant but I took a clearblue and it said notpregnantbjt my friend says they aren't as sensitive and I should get a sensitive pregnancy test considering I've had unprotected sex (didn't know birth control took a month to kick in and condom broke twice) and he said he pulled out and didn't. (No more sex) and just worried because in still late and was supposed to start again the 6th of December. Anyone help me out?
