Help! Do you see a second line??

Danielle

Hi ladies! I’m 12-13 days dpo and two days away from af.. I took a test yesterday and it was clearly negative. I took another one this morning and I think I see a faint line! What do you think? Second question, if it is positive, I have 2.5 weeks left of a 12 week circuit training workout I’ve been doing that’s 25 min a day. Do you think it’s safe to continue or should I stop until I know for sure

?? Thanks in advance!!!
