A condom failure is evident, you don't have to guess it. Please provide us with accurate information to help you better, did you see that your condom was ruptured?
Unless you answer the question, it's obvious to assume that you are very anxious due to fear / guilt and only imagining it broke, mostly that is what happens in such scenarios, we have experienced this on many occasions on this forum.
Any responses please, i know something is happening in my body now and then. Light headed always and body slightly heats now and then
Even with condom failure as far as i know youre chances of getting infected are less. You took pep too, so most probably youre not infected. The light headedness , dizziness part could be because of the side effects of pep. Those are not symptoms of seroconversion either.
