Did your ring size change in the third trimester?

I just got married this week!! We got my rings a size 8, when i’m typically a 7.5 and they’re way too big i’m scared they’re going to fall off. I just hit my third trimester on Tuesday and i’m wondering if your ring size changed in the third trimester and if I should wait to get them resized until after pregnancy? But then I feel like I can’t wear them right now because i’m scared they’re going to fall off. Or, like, if my ring size hasn’t changed thus far in pregnancy it probably won’t anymore? Thanks!
