This will be my third cycle since miscarrying and I have tracked with opks the past 2 to get some understanding of what my body is doing because my cycles are out of whack. I started tracking again yesterday as according to glow I'm 4 days from ovulation (I use the opk analyser function). Yesterday faint lines am and pm, this morning slightly darker (we bd anyway), 5pm slightly darker but still negative thought I'd check before bed and bam! Positive at 930pm. Only cycle day 11 and I possibly would have missed my first positive if I'd waited until morning. Bodies are so weird! Baby dust to you all.
