I have been having brown and light pink spotting for about five days (started 7/23/09) now and my period was suppose to start 7/26/09. I had some cramping and sore breast all last week until Sunday7/26/09. I have been having alot of acne on my forehead which is unusual for me being I have never had acne problems before and I'm 21. Could I be pregnant ? I took a pregnancy test last night and it was negative. Please help.
