I bought an Evacup in the smallest size but I can't use it. It feels like its stretching the inside of my vagina open. Some background on me is that I'm not a virgin but it hurts for about 10 minutes whenever I have sex and I'm not sure how far in my cervix is. I have very small fingers that are maybe 2 inches in length and I put my whole index finger in before I found my cervix. I have no idea why it hurts so bad, I tried every single fold but it hurts no matter what. I'm currently on my period and I can't even use a tampon because I'm so sore from trying the Evacup. Any advice is greatly appreciated!
