Since you attained your natural period soon after the intercourse, you are safe from pregnancy
. Ovulation occurs two weeks prior to the onset of the next period and this is the fertile period when conception can occur. You may have had an early period owing to stress
in the next cycle. Your symptoms could be the usual premenstrual ones. If you continue to bleed irregularly, you need medical help
and should see a specialist for a proper appraisal of the situation. Please try to avoid further intercourse until you heal well and go for regular contraception
. Take care.
