Keep an eye on how itchy is gets and for how long, my gp wanted me to have a blood test as mine waa itchy and it can be associated with your liver (depending where the itch is) alas the itching did subside for me and this did happen when i was about 34 (now 37+3) weeks. Just a heads up for now or the future :)
It means ur streching so moisturise :)
