General pregnancy struggles? 22 weeks

I don’t know if I’m just over worrying or if just typical pregnancy feelings so reaching out in case anyone on here has experienced similar?

I’ve text my midwife this morning to see what she recommends but just waiting for an answer.

I feel generally quite unwell and over the last few days noticed the following are getting worse:

- severe fatigue (literally even climbing the stairs and eating are a huge challenge at the moment)

- dizzy/whoozy spells / feeling blurry eyed

- palpitations

- needing to drink more

- feeling sluggish (like I’ve had a drink or two I feel slow and a little slurred)

I’m scheduled for a diabetes test anyway at 28 weeks due to risk factors (PCOS, BMI, family history of GDM) so I reached out to my midwife this morning to see if the above might need me to be tested a bit sooner than that.

In the meantime I just wanted to see if anyone else had experienced the above and it was just part of pregnancy or something else?
