Hi to you,
First of all congratulation if you are pregnant. There are certain foods you should avoid while pregnant. You need to avoid any food that is raw, such as sushi, eggs or raw meat and fish certain cheese, this could be bad for the baby. No medicine at all even if you are having a headache, the only safe medication is paracetamol. Do not smoke or drink any alcohol. Even certain hair dying products. Why not talk to your midwife for help and advise. Take care and very good luck to you.
