Hi I'm 15 weeks and was hoping to feel great in T2 but for the last week I've felt way worse than T1...suddenly loads of mood swings, freezing cold in the evenings, so so so tired and today nausea has turned into puking. I wouldn't have worried if I was in T1 but should I be worried about these things starting in T2? This is my 2nd baby and never had this before. Any advice so so welcome. Thank you
