Bleeding after sex

Alyssa • Pregnant! Due 8/7/2022

My husband and I have been ttc for one year. I have irregular cycles to begin with, but it seems like right around the time I'm supposed to be ovulating, I lightly bleed after having sex. It's not ovulation bleeding because it happens every time after around the 14th day of my cycle. I'm young and healthy. I do have PCOS. No STD's. don't know what's going on... anyone else?
