Hello everyone! Today is exactly 8 weeks since I stopped feeling sick (morning sickness). Although two days ago, I was throwing up everything I ate and had an ultrasound five days ago. There was a risk of miscarriage, elevated uterine tone (I still have anemia, but my heart beats normally, thank God), and now it's all gone. It worries me that the morning sickness stopped so abruptly. Has anyone else experienced this? Is this normal? Calm me down, I have a scheduled ultrasound at 12 weeks.
