Can Leave taken due to pregnancy complications count against my FMLA for the birth and care of my child?

Yes. If you use Medical Leave for another reason, including a difficult pregnancy, it may be counted as part of your 12-week FMLA entitlement. A pregnant employee may apply for Medical Leave for use intermittently for prenatal examinations or for complications, such as for periods of morning sickness. Medical Leave does not reduce your Parental Leave allowance.
