I get all of this too besides the pain in my chest... its annoying and for me I think its just the extra weight Im carrying all of a sudden.
I mentioned it to my GP two weeks ago when I was ten weeks and he had me down a&e and there was talk of blood clots. It turned out to be nothing.
That being said, as mentioned, I didnt have chest pain.
Do you have pains in the lower legs?
It wont hurt to get a GP appt and ask them what they think xx
