How To Identify That My Hymen Is Broken?

Hi, I have been doing some harsh sports activities for the last two months, I am 20 yo and I ve never had sex or sticked myself with anything, Around couple of days ago, my vagina started to ich me somehow during my period, after one day from washing from my period (which I am completely sure I have finished) I saw some small reddish blood with what looked like a tissue when I pee, and it felt painful when I pee, like if something was burning. I started reading of the possible causes, some results said it could be an infiction and other said it could be the hymen break. I am worried it would be my hymen, and I don t know how I can check by myself and make sure. What are the signs that could tell me whether my hymen was broken or if I got an infection I need to see the doctor for?
