 [ Symptoms ] what do i need to expect when starting my sugar free diet  i have been wanting to quit sugar for awhile now  i consume entirely too much snack cakes sodas cereal etc i was wondering about any dangers or anything that might help me to avoid the cravings that have tripped me up so often in the past thanks [ Disease ] i agree with mrknowles sperm can survive in a warm climate such as your mouth or vagina for up to 7 days & considering the fact that pregnancy symptoms can take weeks or sometimes months to show themselves it is very possible for your girlfriend to be pregnant sir however it is nothing to stress out about babies are wonderful
