need some advise

I've been with my boyfriend for almost 7 months and I experienced a pregnancy scare at the beginning of the month... I never told him about it but I have told him about one I experienced in the past.

When my period finally came a few weeks late it was right before the time I was gonna tell him it was late, but since it came it was just a scare, but I know it messed me up a little bit and IDK... just not sure if I should tell him about it or not
