Which is better??

So me and my SO are gonna try and use ovulation tests, and I was wondering which kind was the best to use?. I've never used them before and i don't know anything about them. I've always checked myself. But we want to try this way. Please help (: we hope this fertile window is the one to give us our rainbow baby❤️
