1st trimester symptoms already!!?

Siobhan

I’m 4 weeks + 5 and the past 5 days I’ve already been needing naps and feeling incredibly nauseous! This is my first, so unsure of what to expect.

I think I’ve always assumed you feel symptoms after 6-8 weeks but I’m only 4! Crazy. How long in your first trimester did you start feeling symptoms?
