From the start of the pregnancy, you are entitled to midwife assistant.
Most midwives offer their extensive services in the form of home visits. Some offer their services at a midwife practice, a birthing house, or even a medical practice. It is a big advantage to use the services of a midwife in the scope of a home visit, if reasons exist to avoid physical overexertion (e.g. premature labor).

Midwife services during pregnancy:
Preliminary consultation, care of pregnant women involving documentation in the maternity log, help during pregnancy-related problems, help during high-risk pregnancies, childbirth preparation in a Group, and individual birth preparation (only possible with medical certificate)
