I know, I know

I suck at blogging. I have had a really hard time getting on here since I created my blog. I haven't even been on WebMD boards either. Something weird is going on down there... WARNING...TMI possible. I am now on CD47. I am pretty sure that I O'd on CD42 but this C has been crazy. I spotted on CD31-34, only upon wiping I saw pink. Then I started spotting again on CD41 and then nothing, until last night. At 9:00, there was nothing in my pantyliner or anywhere and I went to use the bathroom...I gushed out blood, so much I charted heavy thinking good ole AF started. Well, I used my norm, a tampon and I went to RR at 1:00 this morning and was about to change it and nothing more than an itty bitty spot of brown was on it, almost barely there.... SO now I'm confused..>WTH???? Nothing there again today. So I changed it from heavy to spotting on FF..is that right? And what is going on?
