hello i am a 25 years old girl. i had an intercourse on 16th June(Monday) without a condom. so i had i-pill within 2-3 hours. everything was fine. i had a bit of headache. but that was normal, i guess, cause its written on the i-pill cover that it might be a side effect. but on that week i had an intercourse again on 21st June (Saturday). but this time with a condom. this intercourse was a bit rough. after 5-6 hours or so i noticed that i was bleeding a bit. i observed the amount and wore a pad. IS IT MY PERIODS STARTED ? my last period date was 10th of june (my periods occur timely and the duration is for 5-6 days) I AM WORRIED AS AM NOT SURE WHY IS THIS BLEEDING FOR? IS IT PERIODS? THEN WHY IS IT HAPPENING ON THE SAME MONTH AGAIN ? Thank you please guide me
