Is It Normal To Have Blood-tinged Mucus After Using Ex-Lax And A Dulcolax Suppository For Constipation?

I have been constipated for about a week. I ate 2 exlax chocolate pieces yesterday and nothing so this morning when I woke up I used a dulcolax suppository. I had a med sized bowel movement but kept feeling the urge to go several times after. I strained for quite a while and some blood tinged mucous came out. This has happened twice more later in the day. Is this normal?
