Pill question

I went to the Dr. yesterday for a check up. I told him that I was having issues with spotting in-between my period and he told me that I might have polyps (sp?) or a cyst. He changed me from one pill to another (the move it for the wedding) about 8 months ago and thats when the spotting started. He changed me back to my old pills but I am still a little freaked out by the whole thing. He asked me to monitor it while I am on the new pill and let him know if it comes back. If it does, I have to go back for a sonogram

Sorry if this is TMI (too much info)

Maybe it was just your body adjusting ot the new pill. Try not to worry about it, even though I know its hard not to
