First of all, congratulations for your pregnancy. Itching is quite common in pregnancy. You can apply moisturizer or coconut oil to soothe your skin. If it does not help, you should take an obstetrician's advice on the same. Hope this helps to you.
I also faced itching during my first pregnancy. It was quite uncomfortable during that time but then I dealt with it positively. After that I made sure to consult my gynecologist/obstetrician for such issues. Antiseptic creams and certain change in lifestyle and hygiene habits also helped me a lot.
