I didn't find out till i was pregnant

i found out i have Pcos when i found out i was pregnant this year...im now 39 weeks and 6 days pregnant and i found out i had pcos when i went to my second ultra sound for the baby... i had my first ultra sound and they asked if i have irregular periods and i said yes that i have the every other month... then they did an ultra sound baby was on 5 weeks no heart beat yet and i had a cyst on the other side... i was scared because i heard cyst can be dangerous.. then they told me to come next week and they checked cyst was gone heart beat was heard and i was told i have pcos... so basically i had a miracle baby 😅😅
