Rissa,
There is always a possiblity of pregnancy when you have unprotected sex. Now, more information is needed about your cycle, like when was the first day of your last monthly period and to see if you were even fertile (i.e ovulated) around the time of intercourse. Based on a 28 day menstrual cycle if you were fertile around last Friday the 13th ( scary) then you should be expecting your period around the 27th of May. Since it has been only six days since you had sex it really is too soon to be experiencing any
pregnancy symptoms. A fertilized egg takes 7 to 12 days to travel down the fallopian tube and implants in the uterus, which occurs shortly before your period is due. When implantation occurs is when your body starts realizing that it is pregnant. Now with that being said you are not far enough along to detect pregnancy, the first test you can take is a blood pregnancy test at the doctors office, which can detect hCG in your blood as early as 8 to 10 days after ovulation has occured. That would be around the 21st through the 23rd for you and the earlest that you would be able to take a home pregnancy test is around the 27th of May. Now, like I said this is just based on a regular 28 day cycle, more information is needed about your cycle to narrow down your possiblities of pregnancy. So write me back to let me know.
Love,
Falon
