HELP!! 
 I went through a chemical pregnancy recently, AF came like clock work on 7/22 and lasted two days. I started testing for ovulation on 7/24 and I got what looked like a positive, we couldn't BD since we were apart for two days! I tested again on 7/25 and it looked like the test line had faded.. I decided to test again, because someone said it could be the hormones from my chemical that gave me positive ovulation test and on 7/27 I know it wasn't positive, but it started to get dark again! I tested again lol sorry I sound like an addict, but I tested again yesterday and today at the same time and it's not light.. It's not positive, but I'm testing cause GLOW is suggesting I'm in my fertile window and 8/1 will be my most fertile day..
Wtf?!! Help. Side note, all pictures were taken within 3 minutes.
