ovary cyst ?

hi ladies i've been ttc for a few months , we don't ever use protection and he doesn't ever pull out . we have sex maybe 5 times a month when we can see eachother , and sometimes it is on my fertile days but i still haven't gotten pregnant . do you think i could have an ovary cyst ? are there symptoms for that ? and also i drank A LOT of tea everyday for years ... i've had uti's because of all the caffeine and i hardly drank water like ever ... now i'm taking my pills and have stopped drinking tea . could this also be a problem ? please lmk what you think and what i should do . and idk if this is any help but i'm 20 years old . thank you ladies ❤
