Vvvvvvfl or evap on 15dpo

Innu

I have been testing everyday since 10dpo and it’s 15dpo today after taking hcg 5000 injection. 3 says AF late. Everyday getting bfn and today it was so faint that I feel it’s evap line not sure though. Should I test again in the afternoon or wait for tomorrow?? It’s my bday tomorrow so don’t want the day to start of crying 🥲 hoping il get positive tomorrow morning 🤞
