I m pregnant (about 7weeks) and experienced pinkish brown discharge about 2 weeks back. The doc put me on IVF c 5000 per week for 2weeks and diagnosed the situation as threatened early miscarriage. I had an Ultrasound on Thursday at Gestational age 7+3weeks which revealed a large gestational sac with a small foetus. They could not hear the heartbeat so we went for transvaginal U/S where they heard the heartbeat. The doctor seemed to be very concerned about large sac 4.8 by 4.2 and small foetus (6weeks according to U/S) with CRL measuring 0.5cms. They ve called me in for another U/S next week. Does this indicate something serious like an abnormality or miscarriage? Very worried. I m 33, 5ft 3, 60 kg. Have one child 4and half. Experienced threatened miscarriage with him too starting at about 4and a half months. No reason could be diagnosed except the presence of streptococcus B in my urine and vaginal swab tests. Was advised rest and was hospitalized for my first one. Had a healthy baby boy.
