I was in hospital last week as I was having contractions but not dilating. They calmed it all down and I've been fine until today. I woke up uncomfortable, with no appetite and feeling nuseaus. I ate breakfast as I thought I might be hungry and felt a bit better. Now I have a constant period-type pain but strong (nothing like the contractions I had last week). Is it just the babies moving? I feel really rubbish and tearful. Any advice?
