Whole body Edema, headache. 26 weeks

Jennifer

Has anyone been experiencing extreme swelling accompanied with a headache??? I'm 26 weeks. My face, hands, legs, feet have all been swelling. I end every day with a throbbing headache & recently started elevating my head while sleeping. I'm having a harder time breathing when laying down. This is baby #3. I don't remember going through this with previous pregnancies.
