Congratulations on your pregnancy!
At 8 weeks, your 24 hour is a baseline, so it reflects your kidneys' state pre-pregnancy. It doesn't mean you're on the road to preeclampsia (you're only just developing a placenta now), but often, women who have had it in the past have higher than normal protein due to long term effects of the disease. That's why the baseline is done, so they can compare later results--say you get a result of 220 at 32 weeks. Now, if you had had a result of 40 at your baseline, that would be more concerning than if you had a baseline of 210.
