Is frer really better at predicting early pregnancy?

🐘🐘🐘 • 👧🏼 born 1/19/16. 👼🏼 lost 9/15/17. 👼🏼 lost 11/26/17.

I’ve been using the 88 cent Walmart tests for a long time but I keep getting dye runs. I’m 2 days before my next period and I’m really anxious as I’ve had 2 miscarriages this year and I have almost every single early pregnancy symptom. Do you think I’m better off with an frer?
