Will taking the medicine be more painful?

Lucky
I started brown spotting this Sunday and have had very mild(panty liner) bleeding since then with lil cramping. I am thinking to get over with this long uncertain situation by taking medicine but afraid as it might cause severe cramps.
 Could anyone else who has been in similar situation share their experience or give suggestions? Should I just wait or is it the same pain through medicine too? My doc said I can take meds whenever I feel like.
 Feel so struck in between! Thanks to the wonderful ladies out here. I feel so comfortable sharing my feelings. Best wishes for a happy and healthy pregnancy to all!
