TMI Paragard IUD/Missed period

My baby is 14 weeks old. We aren’t wanting another child so I got the paragard at my 6 wk appointment. When ovulating and most of the time I make sure my mans pulls out to be extra careful. There have been a couple times he has not pulled out. I had my period last month and everything was normal. I am now 10 days late on my period and have had stringy clear looking discharge. 3 days before my period I was all grumpy like I always am and cramped a little. Today the discharge had the tiniest amount of blood but was barely visible. Now I’m getting nervous so I’m over thinking. Anyone have any insight?
