Breathless and shaky?

[WeavingWandering]

I’m newly preggie ( Multiple positive tests and I’m still struggling to believe it- it’s been a long journey!) at 3w5d

Today I had about half an hour of feeling really breathless and shaky...

I’m on progesterone (IVF) so have had cramps throughout the 2ww so cant tell if that’s a bad sign or not?

Is that normal?!

Cramps are normal but not sure about the breathless and shaky! Might want to contact GP in case its related to blood pressure or blood sugars?
