I have been using clear blue digital ovulation tests for three months now. I have showed up at peak fertility right on the fourteenth day after period two months in a row. This month I got five high fertility days, on the fifth day, my discharge was clear and stretchy, but on the sixth day it showed low fertility and my discharge was like school glue. I even tested twice to make sure I didn't test wrong and they both showed low. Yesterday I tested again because I was having clear stretchy discharge just to be sure and was at high fertility again. This morning I tested and was still at high fertility. This afternoon I was having the clear stretchy discharge and so I decided to test again and am all of a sudden at peak. I haven't had this happen before. Could this be a sign I'm pregnant, as I am having symptoms but it is hard to tell due to them being the same as a period. I had a miscarriage May 29th of last year and was 10 1/2 weeks. These feel like the same symptoms as before when I found out I was pregnant. But I do not want to get my hopes up. Any advice?
