TMI!!!!! Swollen vagina

Heather • Married to my other half 💒 We have a 6,5 and. 2 year old with 1 on the way in Feb.2016! 😍 Couldn't be happier. ❤️
I am 5 weeks PP. I took a shower yesterday and noticed the opening to my vagina is swollen. It has a large hard lump almost blocking the opening. Does anyone else have this? Or experience with this? Thank you!!!
