Does it get worse with each pregnancy? I had awful sickness (feeling sick constantly, even in the night) up to 20 weeks with my first DS. Couldn't function for the first 15weeks and it came back in the third trimester. With my second child (DD) I had it all the way through. I syllabus felt sick all day long even two weeks before I was induced. I was put on medication but it didn't really work. I would like a third child. Does it usually get worse??
