TMI! - mucus

I don't know how to start this, it'll definitely be TMI. I've been putting it off for a while, but I'd like to know if I'm odd/something wrong.

DS is over 7mths. AF has been back and regular for about the last 5mths. Thing is that in between times my vaginal mucus, is, well, thicker. Really quite thick and opaque. I think it's also more, but it's hard to say because it's not something I've put a lot of time of thought into before.
Is this normal?

At first I thought it was some after baby thing that no one mentioned, because, well, we just don't talk about that sort of thing much do we?
DS was c-section, I had antibiotics in the hospital, and another course just shortly afterwards. Otherwise I feel quite healthy. Oh yeah and should add, it's not odorous.

No personal experience- but.....Could it be a hormonal thang to do with BFing? (if you are- Im not so I dont know)

I have learnt that hormones are responsible for some pretty interesting changes to my own body.

just a thought,.
