On 29th November , I had unprotected sex with my boyfriend. I don't know if he came in me. My last ovulation was on 22nd November . I took postinor-2 on 1st December. I was expecting my period on 5th December. On the evening of 4th Dec I started spotting and on 5th dec there was bleeding but it was lighter than usual periods. It had clots too just like periods. This went on for a week. On 12th Dec I had no discharge at all. I was dry as normal. Since I had sex I have had no symptoms of pregnancy at all. Everything seems normal. I have done a urine test on 13th dec in the morning and it came negative. Today is 14th. I feel normal. No discharge or symptoms. It's been two weeks. Am I pregnant? Am confused.
