Hi, i have a 28-32 days menstrual cycle. i had unprotected sex on the 7-8th day.condom slipped and sperm are spread on the bed sheet, am i pregnant?

Unlikely: Since you would ovulate on days 14, 15 or16, and since sperm is only viable up to 5 days pregnancy would be unlikely. However these are only guidelines and not hard and fast rules as your cycle could vary.

Can't say: However, if you don't wish to be pregnant then would use protection every time you have sex. This time frame is not particularly high risk for conception.
