This is our second month TTC. I’ve been taking LH ovulation tests and taking pictures of them to analyze. Today is day 21 of my cycle and I have a long cycle (last month) was 33 days. According to these tests my LH was increasing and the 16th was the highest but still wasn’t positive, and now the level has dropped. The instructions said to take after 10 am so I’ve been trying to take it between 10-1 to have some consistency. Am I doing something wrong? Could this spike again and I haven’t ovulated yet?
