Hello. Currently 15 dpo. Ovulated December 30th. I took my first test 13 dpo dollar store brand and all negative. Took a few more 14, negative. Then invested in first response to only get another negative result.... is it safe to say I’m not pregnant and wait until af is going to come? I’m still holding on hope that I am? Any success stories of testing after 15 dpo and getting a positive? What do you think? Thanks . As for symtooms I felt Nauseus and fatigued had mild cramping but it’s hard to know , thanks !!!!
