Try benadryl! It helped me and your so far along its perfectly safe
Could be the stretching too.
I had that my first pregnancy, on my feet of all places and nothing relieved it until the baby was born. I mean I tore my feet up! But now this is my third and it never came back.
Mine still itch and my baby is three weeks . I just wear a comfortable bra . And make sure my clothes are double rinsed . Cause I have an allergic reaction to stuff thats not cleaned well
Try coconut oil...it is working really well for me.
Tell ut doctor itching during pregnancy can be a sign of liver trouble
