Is it common to feel tired during week 16?

Yes very normal!! Week 16 is still first trimester/early second trimester, ur body is working super hard to grow baby so feeling exhausted and breathless is totally expected. The breathlessness esp when cooking could also be the smell/heat, a lot of mamas get that. But do mention to ur gynae at the next appt just to rule out anaemia cos that can make u feel extra weak and breathless too. Rest as much as u can and dun push urself, the housework can wait!! 🤍
