bleeding after remicade

I am 50m yo male, had UC now for 6 years.  Now to the point to being on 6-mp,balsalazide (9 pills/day), amd remicade every 2 months.  One thing I noticed is after I get infused, I bleed a little for about 2 days afterwards, but then back to normal (for me, soft, formed stool), has this happened to anyone else? I've seen some improvment with it.   I've been avoiding surgery at least for one more year, if the remicade dosen't help. 

same with me, a couple of days before I get infused..I tons of gas, mucus and cramping.

Same for me..I used ot have infusions monthly ...now every two months... I've never had the bleeding but I usually start getting UC symptoms around the 6th week post Remicade. Then a week later, I get the infusion and it takes a couple of days for me to get back to normal.  I'm booked for surgery in July
