Swollen lips/labia??

So I noticed my right labia is now 3x the size and my left labia is normal. The next day, it would swell down back to normal size, but then it feels like every other day only my right labia(sometimes my left) swells back up and it is extremely uncomfortable!

I brought it up to my doctor and he said it was normal in pregnancy because of blood flow. Is it really just that? I feel like it swells up with the slightest irritation then goes back down then up and I’m not not why it’s just mainly my right lip and it makes me feel insecure.
