Can headaches, a strong sense of smell, and nausea be symptoms at 3 weeks?

Question

I am scared to consider the possibility because I fear it won't happen. Is it possible?

Answer 1

Many times sense of smell increase tremendously while you are pregnany. Alao headaches can occurs for many reasons such as hormonal changes, lack of proper rest, dehydrated. I would recommend resting as much as possible and drinking as close to 2 liters of water per day as possible. Also many people who have morning sickness/trowning up/ nausea,  it can start very early in your pregnancy (also morning sickness is not just in the morning, it can be throughout the day)
