Ovulation Tests?

Kirsten
Hi ladies... And gents!
Are ovulation test kits worth buying? Me and my hubby are wanting to go ahead and try for baby #2 😁
However, I have seen a lot of ovulation test pics on here.... I'm due to get my implant taken out tomorrow (hopefully) if not then on the 12th... It had taken us two months to fall pregnant last time without any help from these tests.... So my question is....
Are they worth buying? If so, which brand? 
Thanks everyone... Sending baby dust and luck your way 😘🙏🏻
