I had unprotected sex 3 days before my period can I be pregnant? As today is 5th day After my periods date but still I din't got my periods. Even I have tested with pregnancy strip but results were negative. Its 9th day after I had unprotected sex. I am worried because I don't want pregnancy. Please help me. Though my partner took care of not ejaculating inside a vagina still there might be some mistake so please help.
