Vaginal swelling

Jessica • Mama to 4 boys and our first little lady :) Evelyn Margaret 3/26/16
The past two days my vagina is so swollen it's very painful. I'm 30w5d. No increase in discharge/smell/color ect, no itching/burning, it does hurt to wipe and everything feels like it's going to "fall out." This is my fourth and I haven't ever experienced this. I do my kegels. 
Anyone else? Any advice? I'm about to freeze myself out and sit on an ice pack 😳
