this happens every time i have my period ...anyone else??

so that’s a blood clot that came out of my vagina when i went pee. this also happened in the shower and I looked down because I heard a sound and it was a big blood clot. when i say big i mean like an inch in diameter but it makes me uncomfortable. i’m only 14 and i talked to my mom about it and she said she would ask an OBGYN friend of hers but it just makes me uncomfortable to think that that’s coming out of me. it happens every month too and idk. can someone help me please
