Any insurance covers pregnancy with a good price?

I will go on a working holiday to Berlin from this October.
Maybe I will fly to Romania, Poland, Hungary or Portugal after spending several months in Germany, if my budget will get tighter.

I’m considering Safetywing/.com for my insurance because it covers anywhere in the world with a good price. The problem is, German embassy requires females to sign an insurance covers medical cost for pregnancy for a working holiday visa.

People in my country write about Care College from Care Concept (care-concept/.de) , but I think it’s valid only when you’re in Germany.

I wonder if there’s any an add-on (free-plan) insurance for pregnancy.
Alternatively, an equivalent insurance with support of pregnancy, and same price range as Safetywing/.com.

Thank you!
