Smile - I start seeing lines up to a week before ovulation.. sometimes they get darker then fainter and then suddenly BAM its twice as dark as the control line.
Then again, with one brand, I got almost no lines, then 4 days before ovulation I started seeing faint lines... then the day before ovulation I saw a darker line but never got a surge. I hate that brand now, lol.
I asked my acupuncturist about the ultrasound thing (she's ordering the test for me this cycle). She said that the technicians are not allowed to tell you what they see.. that they can get sued if they tell you anything. So maybe its best for them if they just don't chat with you so they don't let anything slip, lol.
