Ovulation tests

Sa

Hi all!! Hoping for some advice. We’ve been trying for over 12 months for a baby, I had a miscarriage in August & in December I was over a week late but wouldn’t test, then came on & it was really heavy like my miscarriage so perhaps another one?

Anyway I’ve just finished my January period and I’m hoping to start using Ovulation tests. Question is how many do I need a month? When do I do them? And which ones are best? I’ve ordered some cheapy ones to experiment with (since I don’t know what to do with them). Any advice would be greatly appreciated 😊 xx
