Rabies risk with bat in house. Vaccines?

Hi, I live in Gurgaon. I was working on something 3 days back in my house. Out of nowhere a bat came and started flying over me. I got scared put my hands on head shouted and ran out of the room and closed the door. All doors and windows to outside were closed so where it came is still a mystery. Anyways then we tried to find the bat in the whole room and open the balcony door for it to fly out at night but for 3 days we didn't see it. Today it came out again and flew out finally. Now I did not realise if the bat touched me or not. I slept in other room which i kept closed due to fear most times. Should I take rabies vaccination for this incident? There is no visible wound or anything but i am very scared considering how dangerous rabies is. Can you please help me to understand if i should get vaccines? Its been 4 days but i think it will still be useful if i get it now. Thanks!
