hey anne-marie, its not easy, pregnancy, at all. Have you been taking care of yourself, eating well, sleeping well and so on? What about bloods? I went through a good few weeks of feeling terrible, same thing, crying over everything, no energy, feeling unwell a lot of the time. Turned out I was anemic, once i began iron tablets I was much better.
If there isnt a medical reason for how you are feeling, then dont stress out too much for feeling the way you do. It doesnt automatically mean you will get PND, i had it with summer and was sure i would get it when pregnant with elsie, but even though i was very distressed in her pregnancy too, when she arrived, everything was fine. Please dont be scared to tell the midwife, if she does make a big deal, its only to make sure you get the best of support, should you stay low after baby arrives.
The darker nights and gloomy weather doesnt help a lot either, do you find you get quite low in the winter months? xxx
