Last month I had a positive ovulation test with the at home brand. The stick that you dip into a urine cup. These test are extremely hard to read but I'm 90 percent sure I was ovulating. I had pain and had multiple positive strips. I also tested using the clearblue smiley face digital indicator, but these always come up negative. Could my body be not producing enough hormones for the clearblue to come up positive but producing enough for the at home brand to come up positive?
