I am Manisha, aged 20 I had an intercourse on 2nd march but after almost three months I feel certain symptoms of pregnancy as tender breasts, slightly increased belly, headaches, white discharge for 4 days, mood swings but I am having normal periods. Even my home pregnancy urine test was negative and hcg blood test which I had today was showing less than 2 mIU/ml. so now I am confused whether I am pregnant or not and if the protection used was a failure.
