Hey ladies! Has anyone used different OPK brands and gotten different results from the same urine? I tested yesterday and today using Easy@home and Femometer and got very different results. Yesterday easy@home (bottom pic) had a strong line and femometer was almost there but today femometer had very weak line as if I ovulated earlier in the week. I guess it’s not a big deal but it’s harder to track DPO if you don’t know when you actually ovulated. Has anyone else had this happen to them? Neither test is expired.
