Hi guys, so this month of ttc I decided to use ovulation tests again to see when abouts i get my peak

I took a clear blue ovulation test on Wednesday (Australia time) with my old clear blue stick (as i have being told new ones will say low fertility on their first one as a base result. But when I used my one on Wednesday the screen didnt show anything but i took the test out and it had a vfl so i wasn't ovulating or high. But Today, 2 days later (Saturday morning Aus time) i decided to take a test using the new test stick instead, and I got a solid smiley straight up (like after waiting time) which means i can stop testing already. Now im CD15 so it is abit earlier then normal as I was getting peaks around CD17/18 for the first few cycles of ttc.

Hoping the pre pregnancy tablets are helping and this is my month!!

But is this normal or happened to anyone else?
