I am a healthy 20 year old female, I have been to my doctor because I have not had my period for 3 months. My doctor gave me a blood test and said that everything is normal. I am under a bit of stress though I was before and I still got my period. I am not sexually active.I have been getting daily cramps and have even notice occasional pinkness though no period. Iam not overwight, I weigh about 130 pounds. Can someone please help me with this as it has never happened before and I'm getting scared.
