Should i test again?

Sinead

hi guys, i’m currently on CD 23 and 9dpo. AF is due on sunday, i tested on monday as my boobies were feeling heavy and just had a feeling but it was negative. i’ve since been getting little pains in my lower belly and this morning woke up to a cold sore on my bottom lip. is today still too early to retest? thanks lovelies ❤️
