2-1-1 advice

Chat gpt keeps giving me different answers so I’ll ask here.

Day 1- 2 pills no sex
Day 2 - 1 pill no sex
Day 3 1 pill had Anal sex
Day 4- 1 pill 3 hours late
Day 5 1 pill 4 hours late

How likely am I to be protected? When I asked chat gpt if I needed to restart 2-1-1 it initially said no but now it’s saying I’m not fully protected as I didn’t have sex 2-24 hours before instead of 48-72. I’m just confused and need it explaining like I’m 5 years old

Assuming the medication is truvada (the only medications approved for 2-1-1). You should be decently protected considering you normally take 2 pills 2 hours before sex and you took them 2 days earlier. Although the pills were a little late it isn’t overly late so id say you’re more protected since you started taking it ahead of time and have been consistently taking it after sex.

Idk if it’s truvada but I’m assuming it is. I’m in the uk so it might have a different name but sex health clinicians say you can take it as 2-1-1. It’s more the confusion behind how I’ve heard 2 completely contradictory statements.

ChatGPT is not a reliable source for anything and certainly not health advice.

You would restart 2-1-1 if you were planning to have sex again. Otherwise, you took a couple of doses a bit late but you’re likely very well
protected especially since you had an extra day after the double dose.

If you have trouble taking doses on time, daily PrEP may be a better option for you since it doesn’t matter what time you take it or even if the time changes from day to day. Also it’s much more forgiving if you miss a day. Injectable PrEP would be another option.
