Can I fast for Ramadhan?

I'm in my 2nd pregnancy now and at 6 weeks too like you! Been fasting since the first day cz I'm still feeling fine. 2 years ago I was also pregnant during Ramadhan and alhamdulillah managed to fast the whole mth. I was in my first trimester too but my symptoms were mild with occasional nausea and fatigue. It was a blessing tt time cz it was WFH so I cld fast easily. My Muslim gynae did not stop me frm fasting as he said to follow my body, and take lots of nutritious food. No complications during pregnancy and baby grew well. I delivered a 3.6kg baby in Dec 2020. I'd say follow ur body! Don't force it if u don't feel well but if u're fine, u can fast. Tawakkal and lots of doa.
