So since around 20 weeks my feet have been massively swollen..like to the point that the only shoes I've been able to wear have been flip flops and even those leave divots where the straps go..well I'm now 36 1/2 weeks and yesterday I woke up to only one foot being huge and the other only slightly, today I wake up to one being perfectly normal again and the other only slightly swollen! Has anyone else experienced this?
