Equate Brand OPK’s??

Has anyone used this brand and had any luck? I bought a box to hold me over until my Wondfo ones from amazon get here but I’ve been testing for 2 days and tomorrow starts my fertile week and I’m not even getting a faint line, it’s just literally nothing but the control line. I read online that they are hit or miss and only had 3.7 stars out of 5. Just hoping I’ll start seeing some lines with my new ones🙄 it’s so frustrating, especially since this my first time to try this.
