Ok ladies I had a peak ovulation test on the 26th I then tested until it went completely negative (I'm wierd like that) well today I'm not sure why put I tested with the opk again (6dpo) and it was almost positive! What the heck??? Picture with all tests is my peak test,and then picture with ring is my completely negative opk, the picture with me holding my opk is from today! I'm so confused!!
