I'm 22. I have my last period on 28 Jan 2014. My husband & I have been trying from 5 months but I have got multiple negative urine tests & 1 -ve blood test. I'm gaining weight continuously & getting heartburn & frequent urination. Was diagnosed with PCOS 2 years ago but always had regular periods. This is 1st time that my periods are late. Can I still be pregnant ? Please please please help
