Lifted a small kid bicycle today at 7 weeks

Hey ladies I'm 7 weeks pregnant and went waking with my sister and law and her 2.5 year old today . It was nice to get out and get some some because I'm otherwise inside cooped up all day . Haven't told her I'm pregnant yet and I wasn't helping her at all was not picking up the child at all and when it was time to drop get her off at home I helped her by picking up the child bicycle which was not very heavy but now feel guilty for lifting because I'm worried that I may have harmed my little embryo. What do you all think ? Am I overthinking this too much?
