Evap? Positive? Helppp??

Hannah

Hi! I’m posting on behalf of my best friend! Her and her future hubby (in two weeks they get married lol!) were not trying to convince however they did have sex on the day of her ovulation according to her app and then about 9ish days later she had bleeding she thought it was her period coming she said it was so light but she called me to see (I’m currently 22 weeks pregnant) it looked to me like implantation bleeding brown mixed with pink and not a lot at all. So I tell her to test she takes one this morning at around 4:30am and according to her it was negative then like 5 min later she went to take a pic and it’s positive?? Could this be an evap? Within 5 min seems fast to me and it’s a pretty obvious line. Told her to wait another 2 days and test again just wanted y’all’s opinions!!
