So for a couple days the inside of my vagina has been slightly swollen, today I can barely put my finger in to check cm. I had my period on the 11th and it lasted 4 days which is unusual and it was medium to light. My o starts the 25th. My cervix is high. Not sure if its open or how it feels, couldn't reach it. I've had creamy cm, my cervix has been going from low to high but the last few days it has been high. But my question is, why would the inside be swollen?
