Brown Clots!?!

Jenny
This is my second pregnancy, so I'm aware that brown blood is old blood & nothing to worry about. Well this morning I wiped & had brown discharge, NBD right, well I look in the toilet & there were brown clots!? 
I've also been having brown discharge as well as cramps all day today. 
Doctors office was closed so I have no idea what to do as I didn't go through this with my first. Someone help?!
