<s>[INST] My last period was 25th March. A few days before this period was due, I experienced cramping as if I were about to start my period. I did not. 4 days after I was due to have my period, I had brown and slightly clumpy discharge followed by 2 days of bleeding, which appeared to be triggered by vigorous exercise (lighter than ordinary period). For some time, I have had a large swelling above my pubic bone which feels very hard. Feel odd. Negative pregnancy urine test... Could I be pregnant? [/INST] Hi, i am little confused as you are telling history of march- april and today is 11 june 2013. As per your history, you had periods more than 2 months ago. In case of strong suspicion of pregnancy and negative pregnancy test, one must go for serum beta HCG levels.In my opinion, this will help you to rule out pregnancy. </s>
