Best ovulation tests?

A • ☆ Furmama 🐶 Boss babe ✌🏽

So I had ordered a bulk pack of ovulation tests and have been using them after my 2nd cycle off bc pills and have been unsuccessful to track ovulation. I was really worried I wasn't ovulating at all. I noticed the directions said 2 different things for positive ovulation on the package, so I read the reviews on Amazon and others said to throw them out as they also had faulty tests. Sooo.... I'm looking to buy some ovulation tests somewhat in bulk, anyone have any suggestions on dependable O tests?! Would prefer not to purchase off amazon or ebay this time. Thanks in advance!
