Is it normal to feel tired easily.? I'm 11 weeks

Yes, it's normal. You are growing not only the baby but another organ, the placenta. Fatigue/tiredness is common in the first trimester. Most moms feel better and more energetic come second trimester. ☺️

I just so. Even though I'm currently in week 16 I get sleepy and tired easily.

Totally normal. Im not 14 weeks and been extremely tired since day 1
