I Am In My 3rd Month Of Taking Xarelto For

I am in my 3rd month of taking xarelto for a blood clot. there have been no more symptoms of having a clot & the vascular surgeon my MD had me see , said I may be able to go off them soon. I have for the last week been having red or bloody looking bowel movements. there is no constipation involved , so I'm wondering if me taking an aspirin a day along with the xarelto could be contributing to this. I do ocassionally have hemorrhoids.
