20 weeks and aches

Yesterday and today (now 21 weeks) I have this ache around my belly and sides. It’s not too bad but noticeable. Idk if it’s uterus stretching or anything else!?

Baby has been super active these two days, More than this past week. I’m so happy baby is moving. But I have no energy and i’m feeling down sometimes.

Petrol is expensive this month so haven’t gone out much. I’m getting bored in the house. My neighborhood isnt that nice don’t feel like going for a walk.
