spotting????

Kylie

I have been spotting for 18 days. it started on my predicted period start day, super light and pink but I just figured it'd be a light period. well it's day 18 and today it's heavier than the rest of the days. I'm starting to get worried because this is my fertile window and I haven't ovulated. has this happened to any one else?? im seeing my doctor on the 15th, but I want to know what I should expect. I'm going due not ovulating for a few months.
