Thank you automansgirl for your answer.
But I had very light bleeding for about 3 to 4 hours only 2 days after ovulation.
After that it stopped.
One more thing I realized ovulation(egg white like substance coming out)
While I had sex on the day of ovulation.

If its not implantation bleeding,what is that ?
Is it a problem ?Do I need to consult doctor ?
Or should I wait till my next period ?

Thank you
