Strep B !

What a scary word I heard at the doctors today: 'Strep B'....  I know it's a bacteria which is commonly found in the human body but what does it mean for those who are TTC? Could it affect me? Can it affect my baby during pregnancy Or whilst giving birth? My partner and I are TTC our first baby and this whole Strep B thing has completely disheartened me! The doctor didn't explain much about it which left me coming home and just research about it online which has completely made me feel even worse after reading so much online. 
I'm just trying to find something positive here! Has anyone gone through this? Is it something I should really be worried about? Should I stop TTC?? 😔😔! Help!
