iud miscarriage?

So on the 25th (this Tuesday) I got the liletta iud. They told me I would bleed most likely for maybe a week after. So far I have Not bled once since I got it put in. Yesterday I started cramping but no bleeding and the same thing was going on and I went to the bathroom and wiped and I saw this. When I shined my flashlight on my phone really close to it there's a little clear/veingy part in between the "clot" looking part. All I've had doscharge wise was a cloudy/egg white textured discharge. I would only be like 3/4 weeks pregnant if I was. My son will be 3 months old on may 6th.. please comment what you think!!!
