Super faint line at 7dpo

Laetitia

Hi im at cycle day 21. I have PCOS. And this is the first month of ttc and clomid. Ive been having period like cramps for 2days. Just couldnt resist testing so i went and peed in a cup and dipped the stick🤦🏻‍♀️ now ive done this alot of times before as hy have two beautiful kids. When the urine ran through the test the test line showed immediately dark and went super faint. This is the first time ever this has happend. Im not sure if i ovulated eary with the clomid. Has anyone experienced this and be pregnant????
