Boiled egg is great, full of protein and good for the baby. Just make sure it's fully cooked, hard boiled, no runny yolk during pregnancy. I had one every morning, kept me full and energetic.
Eggs were my protein staple, especially after my morning walk. Boiled is perfect, just cook them well through. Pairs nicely with the protein needs in pregnancy, my dietician recommended two a day.
Eggs are honestly the cheapest good protein you can get, I relied on them a lot. Boil them properly and you're sorted. Cheaper and just as good as fancy protein stuff.
My family always said eggs are good for strength during pregnancy and the doctor agreed. Boiled hard is the safest way, avoid runny yolk. Good source of protein and it's easy on the stomach too.
