is yeast infection pregnancy related?

i got pregnant back in september & around 6dpo i think, i had a yeast infection, i’ve never had one before but i knew what it was when it was happening so i bought monistat 1, i wasn’t trying to get pregnant but when i got the yeast infection that was a sign to me that something was wrong, i’m not 100% sure it was 6dpo based off of the flo app it was but it could’ve been later depending on when i actually ovulated so idk if that’s early for it to b anything with pregnancy, but it was really weird. the ONE time i get a yeast infection i end up pregnant? could that b something that happens that early? now i mentioned how i used monistat 1, you’re not supposed to use monistat 1 in pregnancy obviously i did not knowing i was pregnant & i had a miscarriage 2 days after finding out, i found out at 18dpo cuz i was waiting till the latest my periods ever been, could that have caused the miscarriage? i have a lot of questions. now im concerned that if i did have a yeast infection & that was a symptom or sign of pregnancy, that i’ll have another one next time i get pregnant, which now i am trying to get pregnant & no sign of yeast infection (i know i sound stupid but im actually concerned if that was a real sign for me)
