5 weeks pregnancy

Hi everyone, I’m a first-time mum-to-be and I’m just over 35 years old. I recently had my first ultrasound at 5 weeks, and the doctor said they could only see the gestational sac. Currently, I don’t have many symptoms, except for occasional light-headedness, heartburn, bloating, and my body temperature being over 37°C. I’m wondering if this is normal? Does this count as being pregnant? What should I look out for?#firstmom #FirstTime #firsttimemom #pregnancy
