I recently went to the doctor. the last visit I had an ultrasound. there was no sound of the baby's heartbeat. now the results came become a gestational sac at 6 weeks. afterwards, I also had implantation bleeding that lasts a week. it was bright red, spotting, and mild cramping. now, I talked to my doctor about it, she said it was early pregnancy. all the test results came back normal. even my blood pressure is normal, but i'm still worried, scared and nervous. what's going on I should say what happened to me?
