Help!

I am about 12 DPO, taking a hpt tomorrow morning. This may be TMI but, anyways, while trying to check my cervix I realized that I am extremely tight and swollen/puffy down there to where I could barely get in to check anything at all. Never experienced this before and was wondering what it could be and if it's normal? Thanks!
