Humira (again)

I have a question regarding Humira. I've been on this for 3 weeks now. I just finished my last loading dose of two injections last week. Here is my question. After my initial 4 injections, I noticed a huge change about 3 days after. Symptoms got much better. Maybe only 2-3 bms a day and no blood! That lasted about 3 days, then it was back to normal. I had my next round a week ago Today. The next day I was better again. No blood even a semi-formed stool (possibly thanks to recently starting psyilium root powder, thanks to this board!). Again, that lasted 3 days. Now I'm back to normal, although today has actually been pretty mild. Does anyone know if this is the normal course of Humira working? I feel very encouraged that there is a response, although I'm a little worried that I might be one of those that have to do the injections weekly instead of bi-weekly. I'm trying to be optimistic in thinking this is the normal course of action for it to "kick in" but was wondering if anyone has some insight?

Thanks and sorry for the long rambling post!
