Going to in laws

Ok so situation is next

My husband and I don’t live with his parents we are 20 minutes away.So I’m going there every 3-4 days and I will be there for hour,2 hours.

They have one more daughter in law (she is going there maybe little more than me,I’m pregnant so I just lay down and spend days in the house becuse I have that period to be lazy)

And also they have their daughter and she will visit them after school when she can.

And now my mil doesn’t feel well and they called daughter (she was at my house) to drive her to ER(she didn’t eat since Friday-she had headache, back pain ) .And she went to their house.I called them to see how are things and to tell them I’m sick (just flu sneezing and coughing).So if they need anything they can call.

But am I bad person for not going there more often or that I didn’t go now there (well I can’t be a lot of help)??!
