I'm 24 years old and last night went to a friends house for a drink. When I went to use the restroom I noticed there were several spots of blood in my underwear and when i wiped. This was wierd to me because I got my period 10-7-08 and last night was the 27th. I am usually very regular or even late I have never been this eary. Today I started having light cramps and still just a few spots, when I ate lunch I got neaseaus. I have no tender breasts but do feel "drained". I had never heard of implantaion bleeding until today when I looked this up. I dont want to rush to buy a pregnancy test because I think it could be too early. My fiance and I use unprotected sex but he always pulls out and last time we had sex was about a week ago. So a week after I was off my period. When should I take a test or see a doctor and is this possible to be pregnant by pulling out? :$
