Freaking Out, Help !!!!

I just recently got over a Yeast infection a few days ago. Today i noticed bleeding while wipping myself so i put a tampon in and thought no more of it... I recently just changed it and as i was pulling one out I experienced A LOT Of pain. It's kinda like being constipated rlly bad but 10x worst. So as i began to put anoTher in i could hardly take the pain and it seemed as if the farther up i stuck it the more pain i was in. I hardly bled , which is not normal at all for me.. & i could barely put the tampon in. Im having very bad cramps and pains . Can anyone tell me this pain i am experiencing??
