Sunday my test line was the same as the control. Monday it was darker than the control so I figured that was my positive. I felt the pains and even had a slight temp shift for the past 3 days. I decided to take another opk just to make sure it got faint again. Mine test usually practically disappears after I o. Even before I o it is extremely faint and goes dark the day before my actual surge. Yesterday and today the test was very much darker than the control. I didn't take one Tues so I can only assume it was also positive. My cervix went back to normal low and closed and my cm is creamy. I really believe I o'd Monday (I usually do the same day as my +opk) but how can my surge be that long. Could the B vitamins I'm taking be causing this?
