10dpo.... faint positive?

Lydia

Had a positive OPK on August 31st with what I’m assuming was ovulation pain right side my period is not due for about 4 days but I have been having really severe pain tenderness in my boobs, some foods make me feel sick, super super tired, dizzy.. so I decided to take a test early this morning with FMU and it was negative. This afternoon however I took this test and there is a faint pink line.. could it be a true positive? I plan to test again in the morning just wanted to see what others thought.
