Hello, I had a miscarriage at around 7.5 weeks though had brown bleeding from 6 weeks. I am just wondering when does my cycle day start? Would it be Friday 17th November when I first got red blood and bad cramps? Or Sunday 19th November when I passed the sac? I thought I would have got a peak LH surge now (usually get them between day 12 -15) but it's very low today and seems to be fluctuating.
