Hjörr pregnancy one time only? [0.7.15]

[MyOldName]

I don't seem to be able to get impregnated a second time by Hjörr. The first time I get pregnant and later gave birth. The next time I tried, I was unable to get pregnant. After that failed attempt I've been impregnated by Tetsuya, so the plumbing downstairs should be OK. I walk to her square, press [Hjörr] -> [Sex] -> [Get Bred]. Am I missing something?

It's repeatable, done so with my main save.
