I had IVF transfer on 12/10. Everything has been going well positive pregnancy. I am considered 6 wks pregnant yesterday 1/2. Yesterday I started having a small to moderate amount of dark brownish discharge. No red or cramping. However, very scary. I have my first ultrasound scheduled for tomorrow 1/4. I left a message for the IVF nurse however have not heard back as of yet. I have read that this is normal however, just wanted to put the question out there with my other fertility community and see if anyone has experienced this.
