It does sound normal. Mines like that all the time. But i had it with my first too. If ur concerned just mention it at ur appt. X
You might have a yeast infection.. Most doctor offices have nurses you can call and talk to and they are really helpful.. When you go to your apt have them do a pap if they aren't going to already, it will give you piece of mind..
I agree, sounds like a yeast infection!
