Hi....yesterday I thought i began my period because when I went to the washroom, and wiped myself, there was mucus and blood...this went on throughout the day. It stopped this morning, but happened again tonight. I do find that everytime I work my abs, I tend to get some spotting. I'm also on thyroid pills (if that has anything to do with it). One more thiing to mention...I just got off antibiotics because I had a UTI.....thanks in advance for your help
