Birth control and plan b/aftera

Angelica

I am on the pill (Tri-sprintec, on the 3rd month right now and plan to be on it for a while) and I had unprotected sex on feb 14.. I’ve been late on taking my pill (by an hr/hr & a half) a few of times last month and this week.. (ive NEVER missed a dosage though!) so I’m wondering, should I still take plan b/aftera as a precaution and continue my daily pill or would I be safe with just my daily pill??
