I feel mainly happy and calm during the day (the odd emotional moment or grumpy day aside). When the evening comes however I start to feel really anxious. Has anyone else had this? I don't want to feel that way as I am sure it can't be good for the baby. I really don't know what is causing it - the only thing I can think of is I am not sleeping well so perhaps it is related to that. I don't have to get up in the morning though so it's not a big stress that I can't sleep at night.
