Accidentally ate an edible at 28 weeks and now I’m freaking out

EDIT: In Iowa, some hospitals will drug test ALL baby’s umbilical cords after birth, while others only test if there’s suspicion of drug use during pregnancy. I’m not sure if my hospital will, but I have also read it takes 20 weeks to clear out of the umbilical cord.

For context, I live in Iowa where THC is illegal and when I look things up about my baby testing positive, it sounds like I could be put on a child abuse registry and all this stuff.

So I’m currently a little over 28 weeks pregnant and sick with a cold. I went to stay at my parent’s house for the weekend and woke up in the middle of the night and desperately needed a snack. There were some cookies in a Tupperware container(my mom bakes a lot so I figured she had made them) so I grabbed two and chowed down before going back to bed. I can’t taste or smell anything right now, so before anyone asks, no, I didn’t smell or taste THC 🤦🏼‍♀️ But the next morning my stepdad came into my room freaking out and asking if I ate any of the cookies. I told him I had two in the middle of the night and he tells me he got those cookies from a friend and they were pot cookies. I’m a heavyset woman as it is and I don’t have like 10 weeks before I give birth. I’m so scared now that we’re going to test positive and I’ll be put on a child abuse registry and have to go through a bunch of stuff with CPS. I know there isn’t much I can do, I just wanna hear from other people and know I’m not a terrible person 😭
