Murph I think someone else started a thread on this recently as well, if I remember correctly (as it seems so long ago) but the first one can be really heavy and in your case there has been a lot of time for it to "build up" shall we say. Hopefully it will slow down for you, but keep an eye on if it keeps on going I'd get it checked out to make sure you don't get anemic (sp??) especially seeing you are still BFing.
