I'm so confused, this is so emotionally taxing. I ovulated on the 19th or the 20th of this month, and my LH levels dropped off promptly like normal. Then yesterday and today I get dark lines, total positives on my opks again. I did 3 throughout yesterday, all the same. Did one this morning at 5am; still the same intensity. I am on cd 18 and 8dpo
