I'm 30 year old woman and newly married.Usually my periods comes on time and never gave me a trouble.I got my last period on August 21st and it last for about 6-7 days.Then I had few intercourses with my husband and we never used any protection.Yesterday (2nd September)he ejaculated in me and suddenly I realised it could be my fertility day.But after few hours I saw some bleeding in my panty.The whole through the day I had a little bit bleeding.What can this be?I'm really worrying and I'm planning to have a kid pretty soon too.Let me know what can be this bleeding?
Thanks

Most likely your fertility day is 11 - 14 days after the onset of the first day of your last period. So, you are within that range. The bleeding is most likely due to a little rough sex maybe where his penis or ejaculate caused some inflammation of the cervix. This is not unusual and nothing to worry about. But it does look as though you had unprotected sex during your fertile cycle.
