Yeah, but because they keep on doing it with such an enthusiam everyday he get pregnant . And now in a serious note, For what i can intuit Miyauchi was raped during his childhood until he was taken in by the Aoi's household and then after that he had to do it with alphas who were after Aoi to protect him, that's right?
For those confused about Miyauchi's fertility and the doctor visit flashback.
Anyone can get pregnant in Omegaverse, it's just that the fertility rate varies.
Omegas have the highest fertility rate especially during their heat, betas have a lower rate but they can still give birth and alphas have the lowest rates. These are generally the rules for all omegaverses(including this one) though it can also vary by publisher or author.
The reason Miyauchi went to the doctor was because he wanted to bear Kudou's child but when he found out he would have trouble conceiving he questioned whether he would be able to make Kudou happy. The doctor told him he would have a bit of hard time conceiving a child because of his traumatic past, it's not because he's a beta.

PS.
Please be polite and respectful and don't tell her some insensitive thing like " I love your manga and read it on Mangago" or any other illegal manga site. Remember there's no official translation for this series, so if you didn't buy it and read it in Japanese you read it illegally. I know it's common sense but I've seen dumb people do this before.
