Hi I'm 6 weeks pregnant, during my 4th week I was having all the symptoms of pregnancy like sore breast, metallic taste, strong sense of smell, fatigue but never nausea. I took 3 preg test all came up positive. Then now my symptoms are wearing off, am I having a misscarriage? But I have no spotting, just occasional cramping that doesn't last for more than a minute and pressure on my lower abdomen,Or is this normal? Thank u
