Hello.. Sorry about the picture/TMI but went to the bathroom and after I wiped I saw this slippery mucus.. My period is late for a month now. I was on birth control and I stopped it I had the withdrawal bleeding. That's was around August 8th. I have cramps for the past 2 days. I took a test on September 1st but was negative. Should I take another one or this a sign my period should start soon? Thanks
