Rashes-like in thigh and legs

Hi! I'm at my 13 weeks now and I'm worried. I have this itching at the back of my legs and in my thighs. It's like rashes. I don't have food allergens . According to my friend who is also pregnant but in 26 weeks, she also experience itching of the body on her 1st trimester. I just wanted to know if you guys also experience it? I can't go to my OB because of lockdown.
