Don't worry, I "saw red" too when 2mths for 1 mth and I have the B type virus too. My baby is now 8 months already. Take the medicine and they will do injection to protect BB when giving birth.
My BB is very healthy now. Wanna see her video, I can show you so that you don't need to worry. PM me if you want to see. OK? Believe me and you should have confident to your BB as well, she / he knows.
