miscarriage blues or pregnant???

Carlita
So the first week of April my husband and I experienced a miscarriage at 7 weeks . I took a test 3 days before my ob appointment and it came back positive but when they did a test it came back negative. I followed up with my obgyn a few days later. She gave me and ultrasound and advised everything looks healthy . On the ultrasound she showed me my uterus the blood flow and even an egg that was sitting in my tube. She ordered blood work and it came back at a 9.4 so I will retest in two weeks . A week later I've been experiencing increase in appitite, fatigue, more mucus coming out, very bad headaches  & cramping . Am I crazy but could I possibly be pregnant again.
