Iud tmi: possible miscarriage?

So I’ve had my iud for about a year now and recently was on two different antibiotics back to back as well as daily anti-depressants for my anxiety. I’ve heard and read that although the iud is the most reliable form of birth control that these medications I was on can cause them to be less effective. I have obviously had unprotected sex where my so didn’t pull out and have had cramping, sore boobs, more discharge than normal, and some nausea. I have a one year old and these are some of the same symptoms I had when I was pregnant with her, but I am also aware that this could be pms as well. I don’t have a period on my Mirena. Just spotting every couple months or so. The picture is below from when I wiped earlier. I would also like to note that until earlier I was not concerned about the possibility of being pregnant and haven’t taken a test. I would just like some of you ladies opinions please. And please no negative comments or remarks as we are all here for the same reason and we should lift each other up and help one another when we can instead of tearing the other down. Thanks in advance.
