So the past couple of days I have been having a lot a creamy discharge. Yesterday I had to change my panties like 2-3 times because there was a lot of discharge plus I heard from someone that a bruising feeling on yur tummy is normal because its stretching. Thats the best definition I can give to what it feels like. Is either of these normal?....Please help....
