Bleeding during pregnancy

Currently 35 weeks pregnant, with a babyboy & it's my first pregnancy so I am very anxious. Yesterday when I had sexual intercourse with my partner, I bled abit ; no more bleeding subsequently. Didn't went to seek medical help up till now because the baby is still very active and I can't afford to keep going to the hospital, also my bill at the hospital has been accumulating so Im afraid they wouldn't allow me to see the doctor ( my msw application still in process ). But I am quite worried about the bleeding eventhough it was a one time thing 🥴
