Unfortunately, like with any medical procedure, there can be complications after IVF implantation. Bleeding is often cause for alarm because it is one of the first signs of a miscarriage. If you start bleeding heavily after your IVF transfer, seek medical attention. However, spotting after an IVF transfer may be a sign that the procedure has taken. So how do you know the difference?

Is It Normal to Get Heavy Implantation Bleeding?

No, heavy bleeding after an IVF transfer is not normal. Implantation bleeding is normal and so is spotting 8 days after an IVF transfer, but bleeding should not be heavy. Light pink or rust-colored spotting is no cause for alarm.

Other Causes for Heavy Implantation Bleeding

Implantation bleeding is light bleeding that may occur after IVF when the fertilized egg implants in your uterine lining. If you experience heavy bleeding, it could be a symptom of the following:

  • Bleeding disorders like Hemophilia, von Willebrand disease
  • Cervical infection or sexually transmitted infection
  • Ectopic pregnancy, which happens when the fertilized egg implants itself outside the uterus
  • Uterine cancer, although rare, can cause symptoms similar to implantation bleeding
  • Uterine fibroids are noncancerous uterine growths that can cause bleeding
  • Uterine polyps may bleed due to hormonal changes

Conclusion: When Should You See a Doctor?

Light implantation bleeding after an IVF is normal and can be one of the earliest signs of pregnancy. Seek medical attention if you have gone through the steps of the IVF timeline and you are experiencing heavy bleeding, dark red blood, or clotting.

Heavy bleeding on day 10 or 11 after an embryo transfer isn’t normal and may be a symptom of an underlying issue, so make an appointment with your healthcare provider.
