Can anyone help me understand?

I track with both glow and just on my own planner because it’s easier to show my doctors that way. Anyways. This cycle is weird. I have had multiple positive OPKs and normally I trust the first one, but this cycle on Aug 7th at 9:00am from the same urine I had a test be positive and another negative. I only did two tests because the first one just seemed a little off. The dye was taking a long time to travel. The positive wasn’t super positive like it was last cycle either. I didn’t test the 8th or 9th, but then I had so much EWCM I decided to test again. I had another positive on the 10th around 10 or 11am and became instantly positive with equal lines (last cycle the test line was darker than the control). By 6pm the positive was gone. I’ve been spotting since the 8th and had EWCM at least once a day since then as well. I’m on letrozole 5.0mg. I had bloodwork done today to test my progesterone and I’m still waiting for results. I’ve never heard of someone having mid cycle spotting for this long.

Main questions:

1. When do you think I ovulated?

2. Ideas as to why I’m spotting?

3. Why so many days of EWCM?

Normally my weight spikes up when I’ve ovulated but it hasn’t-think that’s just another sign I have not ovulated?
