Hi, I had MM on 1st April, but then bled a few days, then spotted a few days, then bled a couple of days, then spotted for a while, then nothing, so I don't even know when I was supposed to count from!
The nothing lasted just over two weeks when I started feeling awful, thought I was just struggling with my job, then after a few days of that thought it felt a bit like the worst PMT ever. Then spotted a bit for several days, and wondered whether I was having a very light period. The bleeding didn't seem like a period, but the PMT, and then the easing of PMT as the spotting started seemed like a period. I just felt like I just "knew" it was my period, nothing else really made sense.
Then on Monday after a few days of spotting it turned into normal period flow. Tuesday was really heavy for me, but today just seems like a normal period.
So as I say I don't really know when to count from in terms of when the bleeding stopped (they say 21+ days after bleeding stopping, but you may still spot after that) or indeed when to count my AF as starting! So for me it's a bit weird, but kinda came sooner than I thought it would. Maybe that helps you a bit?!!
