Feeling off?

Asides from the aches and pains of pregnancy is anyone else finding themselves just generally feeling off?

I last had my BP/water checked on Friday at my growth scan but since then I’ve been struggling on / off with headaches and occasional spots in my vision. And I just feel really slow/lethargic like my body isn’t keeping pace with me kind of thing? It’s like I’m really having to think about what I’m trying to do.

I don’t think I’m sick, and have been testing regularly for covid but I just don’t feel myself and don’t know if it’s just one of those pregnancy things or something to look further into. I did go back to work yesterday after the Xmas break so maybe it’s just getting back into the rhythm but I feel so out of sorts I’m hungry but nothing appeals to me, I wanna lie down but I get uncomfortable

I see my midwife again tomorrow anyway so my water/BP etc will be checked again but everything normally comes back just fine.
