Swollen ankle!

Today I noticed that my right ankle is suddenly swollen but my left is not at all.. also, Sunday morning I woke up to my right eye sight was very blurry, I couldn’t see out of it for 45 mins but I don’t know know if it has anything to do with my swollen (I don’t think anyways) & pretty sure it was maybe I slept a certain way for this to happen. My next OB appointment isn’t until feb 15th so I don’t know if this is a concern to call them plus I live like 20 mins away from my OB & really don’t have the gas to waste a trip for nothing & I have a feeling their just going to tell me to come in like always. I am currently 34 weeks pregnant. I haven’t done anything like walking or being on my feet for too long or wearing tight socks/shoes, I seriously have been just laying down. My ankle was not swollen yesterday, it literally just happened today & I’m not able to take my BP to see if it is normal. Should I be concerned? Or is it just another pregnancy symptom that we have to deal with?
