So im about 7 weeks pregant, i think and since the week before i got my positive pregancy test I have been freezing and really struggle to get a heat in me, has anyone else experienced this?

Also been fed up, crying hating everything flying off the handle and just wanna know if this will pass. What's everyones experiences this is my second pregancy, my first pregancy i actaully had more or less no symptoms apart from an itch( which was never really diagnosed, and left the second i had my Csection) and my mood was amazing, only time I was upset was when my FIL passed away, which is obv understandable. And i hate acting like this crazy lady in front of my son as i dont want him brought up in that environment and then i get more angry and upset with myself as I have acted angrily or upset in front of him :(
