Hello Doctor. I'm Currently On HIV PEP, And I Was

Hello Doctor. I'm currently on HIV PEP, and I was taking my pills everyday at 5pm (Lamevudine, Tenofovir, Atazanavir, Norvir). This morning, because of strong evidence, I thought I had missed my dose yesterday, so I took the pills at 11am. Then I found other evidence that suggested I had not missed that dose. So, basically, now I don't know if I missed my dose yesterday at 5pm (I'm almost literally 50/50% on this, siding to the possibility that I did miss it), and I took a dose today at 11am. What should I do now? Extra information: I did not had any perceivable colateral effect since the beggining of the treatment (I'm 18 days in), aside from a bit softer fezes and yellowish skin (but every other blood exam result aside from bilirubin showed perfect liver functions. The high bilirubin is because I was more susceptible given I have Gilbert's Syndrom). Just thought this might be relevant to and eventual decision that the risk of overdosing might be better than underdosing.
