New Tester or not ovulating?
I just started using clearblue ovulation tests. This is my second cycle. Last month I tested positive for my surge, but was later than I thought. I had a blinking face for four days before I actual had the solid one. This month I have not had any faces, only the blank circle. Last month I started getting the blinking face on day 14 and had my surge on day 18. Right now I am on day 21 and still nothing. I am taking medication that is supposed to be helping me ovulate, so I assumed I was. My question is: After testing positive, do I need to get a new tester? I am still using the same one that tested positive from last month because I had leftover sticks. Thanks!
