Waking up to swollen ankles?

This is my 3rd pregnancy and it's the first time something like this happened to me. I had slightly swollen ankles yesterday but after I put my feet up and hubby rubbed them a bit of went away. Well when I woke up this morning they were back, it's not as much as I see many woman posting but it's a visible swelling and was wondering if I should get my blood pressure taken? The only problem is I have to go to the doctor to do it since this country I live in is ridiculous and pharmacists don't offer that option, that's why I'm asking here. I'm 34 weeks.
