Can I fast for Ramadhan?

Firstly, take note that pregnant and breastfeeding women are not obligated to fast as we are caring for our child. Secondly, ask your doctor first for advice just in case if there are some health concerns during your pregnancy. Since you are at your first trimester, might be inadvisable. Thirdly, if you do attempt to fast, make sure it is high in nutrition and you get fully hydrated. Watch for red flags while fasting such as dizziness, very yellow pee, etc. Many women can manage to fast at various stages with no problem and some cannot. Don't feel bad. I, myself did not fast for both pregnancies at 2nd trimester as I tend to feel light headed and it is not safe for me, especially I am also carrying my first child.
