Cervical mucas NO PIC

New to this so any help would be appreciated.
I'm not actually ttc in fact we're trying to avoid it.
I'm 7weeks PP and EBF  
We (stupidly) had unprotected sex 2 days ago, I noticed I'm having EWCM, that's the most fertile right? I'm not sure what it looked like the days before and during the time we had sex. Today it was a little bloody. What does this mean! 
To say I'm shitting it is a major understatement
