A little backstory. I started ttc in October and I used the Walmart brand opks. Got pregnant that first month. Sadly at my first ultrasound appointment baby didn't have a heartbeat and stopped growing weeks before. So I had a missed miscarriage which resulted in me getting a d&c. For the past 6 months I have tried both brands of clearblue digital opks along with the wondfo brand opks and I'm still not pregnant. Not having any luck at all like I did with he Walmart brand. I'm thinking about trying the Walmart brand again but I feel like I'm stuck behind a wall and not sure what to do. I stopped taking my vitamins because I was getting discouraged. I've tried preseed. Sex on my fertile days.. and still nothing
