Hi Doctors! So usually I had regular cycle of 28 days but from last month my cycle got delayed and period arrived on 37 days and this month today is my 37th day of cycle and haven't got my periods yet. I have done pregnancy test in the afternoon it was negative. I have been trying for a pregnancy for more than a year now. Symptoms I currently have is- Backache and abdominal pain coming and going not persistent. One side headache, skin is very itchy at night, nasal congestion coming and going, breast pain. What all symptoms is this? Is my period going to come or am I Pregnant? Please help.
