My husband and I have been trying to get pregnant since January. I test 2-3 times a day and I got my first positive ovulation test for this month on March 1st, it is now the 7th and both of my tests (digital & strip) are still surging strong?! Has anyone else ever surged for 7 days straight? I’m not sure what is going on. The attached picture is the last set I took this evening and the lines are still really dark. I took a pregnancy test to be sure and it is negative. Any advise?
