With my first pregnancy, I used clear blue digital ovulation tests. while that worked, they were pricey. This time around, I'm trying the Easy @ Home Opk strips because they're way cheaper and you get so many that you can test more than once a day. I got the 50 OPK/20 Hcg strips from Amazon for about 20 bucks. I've read good reviews on them so decided to try. I've also heard good reviews about Wondfo. Good luck and sending baby dust your way! 😊
