Hello, Thanks for asking your question in HCM. I can understand your concern. I want to tell you that itching is very common during mid pregnancy and it will continue through out your pregnancy, so this is absolutely normal phenomenon and you need not to be more concerned about this. Itching will lead to scratching and stretching of your skin and it will lead to red bruise like spots specially around your flanks, abdomen, back and sometimes on limbs also. You just need to apply bio oil to get rid off your itching and red stretch marks. You can also apply coconut oil, olive oil or any moisturizer, whichever suits you. Don t keep your body dry, otherwise itching will increase. So don t get tensed and you are not having any kind of allergy. Best wishes and best of luck for your pregnancy.
