2 pills only in first dose of yuzpe method

Problem/Goal:

Hello po! I need advice!

Me and my boyfriend had unprotected sex yesterday. But then he would put on a protection before he could ejaculate. After several hours, I only took 2 pills (8PM) instead of 4 pills, because I didn't know I had to take 4. After 12hrs (at 8AM kanina) I took 4 pills and then my plan is to wait for another 12hrs to take another 4 pills. I'm very anxious right now! I used Trust pills for the Yuzpe Method.
