Swelling & when is too much swelling?

So I’ve been on my feet more than usually this past weekend from baby showers & getting her room ready. I’ll be 35 weeks tomorrow. I just now started noticing swelling. But it’s in my fingers & toes only. Like this morning I woke up to my fingers throbbing and took off my ring. I’m worried about preeclampsia but my blood pressure has been good every doctor visit. Just when is it too much? & is it normal for your fingers to be swollen when you first wake up?
