Pregnancy: You could so do a pregnancy test and good luck

Well,..: You are getting close to the window of opportunity, and sperm may live for several days in the right environment like that of the warm vagina,..so there is always the chance.

Yes.: If you actually miss your period, do a home pregnancy test. If you aren't pregnant this time, and you don't want to be pregnant, you need to change your behavior to avoid pregnancy, and not rely on luck.

Pregnant: Yes, you may be pregnant. Purchase a pregnancy test to find out for sure

Doubtful: Sperm can live 4-5 days inside the female. If you ovulated six days after intercourse the odds are you are not pregnant. Spotting and nausea are probably meaningless. Plan B is 90% effective within 72 hours after intercourse. You have missed that window. I would wait until my period is due and take a home pregnancy test if necessary. You might be pregnant but the odds are against it.
