I had oral sex. But he was wearing his undergarments when he put his dick inside bt I didn't think it get too inside mine because there wasn't any such pain and any blood at that time. My period date has not arrived yet moreover in last few days I was having cold due to which I was having headache and sometimes little temperature also. And also some times I feel little irritation or kind of pain in my breast. I am feeling that I am thinking 2 much about it and 2 worried about it that's why this is happening. Is there any chance of pregnancy. Or I am just over thinking. Can you please help me.
