Took 2 hpt as one had a mark on it and one opk & used it as a hpt. I'm 9dpo and at first tests looked negative but went back after 20 min or so and I swear I could see a second line! Please tell me I'm not suffering from line eyes! I'm posting several pics so that you can choose the best quality one. Thank you.
