My name is Jenny. I'm 30 and have been married for 3 years. My hubby and I had a miscarriage at 11 weeks in November. We stayed ttc again a couple months ago. I am wanting to buy bulk opk and hpt because after only a couple months I've spent a lot of money. I know I've seen posts about ladies buying bulk on Amazon. What brand and did they work??? Please help me save my hard earned money. Thank you!!
