31 weeks and feeling strange

The past week I have just felt off. It's hard to explain. I have no energy, motivation. A constant fuzzy headache which paracetamol doesn't touch. I wake in a morning and can barely move from being so achey. My feet and hands are swollen in mornings too. My vision seems blurry sometimes too.

I've been to midwife and they did preclampsia tests a few weeks ago and they're not worried - no protein in urine and blood pressure fine.

I suffer from heart palpitations too which don't go away until baby is born.

Do you think I should get back in touch with midwife? I know it sounds weird, but I just feel off.
