I've been having a regular 28 day cycle for quite some time now, and my periods were always on time (sometimes 1 day late). My last ''regular'' cycle fell on June 17 lasting 6 days, and a regular flow,which is normal for me. My next period was due on July 14th. However, on the 10th I had a brown mucus discharge, but only when I wiped. This has never happened before. On the 11th through 13th, I had a period that seemed a little watery. I counted 28 days from the 10th, estimating my next period to fall on August 6th, but I started spotting a creamy-pink mucus discharge this past Saturday on the 28th. I started spotting red, almost watery blood Sunday night. It started to get heavier,and darker on Monday. Today it is still a little dark, but a lesser flow. With my first pregnancy, ''years ago'', I didn't have any spotting or discharges. I had what was to me a normal period as usual. When I did find out I was actually pregnant, I was already 3 1/2 months. I have read about implantation bleeding, and that it would be either pink or dark brown, and would last only 1 or 3 days. I've also read and heard that some women have vaginal bleeding and think it's their regular periods and don't realize they are actually pregnant. Please excuse the rambling. My main question is, with this odd cycle, could this possibly be implantation bleeding or something else like perimenopause. I am in my mid 40's.
