The : The spotting you experienced could be implantation bleeding. Implantation bleeding is a small amount of pink/brown spotting some women will experience when the fertilized egg implants into the uterus - an early sign of pregnancy. The only way to tell whether you are pregnant or not is to take a pregnancy test. As doctors, the first thing we do when we hear a woman is having a light or missed period or abnormal spotting, we check a pregnancy test. You can either take a home pregnancy test as long as it has been 5- 6 weeks since your last normal period, or you can go see your doctor and they can test you. A home pregnancy test is 97% accurate if taken a week or more after the missed period. A blood test can tell if you are pregnant as soon as 7 days after conception and a doctor's urine pregnancy test can tell if you are pregnant around when you next period should come. Of course, whether or not you are pregnant doesn't affect whether you could have an std also. You should talk to your doctor about std testing and use condoms to protect yourself in the future. Good luck!
