Today as i went to the bathrrom i noticed a big clump of mucus. The first thing i thought of was pregnancy. Since there was a hint of pink in it. Although since yesterday i have had mild cramps but i know it can also mean implantation. My last period was around december 27. I ahev very irregular periods and my last before thAt was in october. I started taking birth control pills in december. So is this mucus something i should worrie about? or could it be something diffrent. ANY HELP WOULD BE GREAT
