Iud and Condom But Am I Seeing Signs of Early Preg?

So Thursday me and my boyfriend had sex but I got an iud placed a little over a month ago and we used a condom. Saturday I got a super light period like brown and bright red blood but I am scared it is implantation bleeding. It barely filled one tampon and today I had brown and bright red again on my tampon but it wasn’t that much. Is this implantation bleeding? I don’t know why I am so scared but please help a girl out. The condom didn’t break or anything but what if it had a hole or something??
