belastete Vorgeschichte

I agree, "complex" or "complicated history" seems to be the best solution. Why don't you propose an answer, Sanni?

...as it was phrased in the question, I assumed this was specifically about pregnancy.

In any case, maybe this helps:
"Diagnostik 'unbelasteter' Frauen:

Bei Frauen 'ohne Vorgeschichte' (keine Eileiterschwangerschaft, Entzündung, Endometriose, negativer Chlamydienbefund) kann die Eileiteruntersuchung durch Ultraschalltechniken (Hysterosalpingo-Kontrast-Ultrasonographie) durchgeführt werden...
Diagnostik 'vorbelasteter' Frauen:
Nach den derzeit vorliegenden Studien sollte Frauen mit vorausgegangener Eileiterschwangerschaft, mit Entzündungen, mit Endometriose oder mit positivem Chlamydienbefund die Bauchspiegelung angeboten werden...
Nach bestem Kenntnisstand wird bei Frauen 'ohne belastete Vorgeschichte' die Eileiterdurchgängigkeit durch eine Ultraschalltechnik untersucht. Die Untersuchung auf Chlamydien (häufige Ursache von Eileiterentzündungen und von Tubenverschluss) ist zusätzlich erforderlich."

This is nonspecific. I would consider "complex medical history" (Sanni, below) or "complicated medical history."

The "belastete Vorgeschichte" is not described in detail. It could therefore refer to other health problems, unrelated to a difficult pregnancy. The sentence reads: "Bei Verdacht auf Schädigung des Fetus oder bei belasteter Vorgeschichte umfasst eine eingehende Ultraschalluntersuchung, eine Untersuchung des fetalen Herzens durch farbkodierte Echokardiographie."

Several articles in the OB-GYN literature support Sanni's suggestion of "history of complicated pregnacies" as in: https://cdn.journals.lww.com/greenjournal/Fulltext/2015/0600...

I think that Sanni's suggestion of "history of complicated pregnancies" is also used frequently in this context.

Can you conclude from your source text, whether the author wishes to indicate that the pregnant woman suffers mental stress due to complications during previous pregnancies, or is he/she saying, previous complications make this woman a medical high-risk patient, and we have to watch out for complications during pregnancy and delivery? – The "best" translation would be different in either case, IMO.

If the medical history only relates to the pregnancies, you could simply say something like "has a history of complicated pregnancies", if the pregnancies were complicated because of other health issues ,you could say, "complex medical history"
