Ovulation prediction kit

Desiree • I`m 30, been married for 2yrs now and we are ttc for #2 together. My hubby doesn`t believe in stepparents and loves my 12yr old son as his own. Yup I`m blessed!!
So I went and saw my doctor today to go over some lab results and an ultrasound and thank God everything is normal. She suggested that I get some ovulation prediction kits. Has anyone used them and if so what was the out come for you? She is confident that we will be able to conceive naturally which was great to hear. Any feedback would be great. Blessings to you all!!
