Taking PrEP is not a decision that you should be leaving up to comments in this, or any online forum. You need to discuss this decision, and dosing, with a doctor. We cannot advise you on how to take prescription medication ad-hoc.
Regarding your bumps - symptoms are not used to diagnose HIV. If you have had a risk, take a test at the appropriate time to know your status.
Let's think about this logically. You said in this thread that the encounter was with a person who just tested NEGATIVE for HIV. So, if she is negative for HIV, then it would be impossible to get HIV. Even if she were positive, your risk level is less than 2% which means extremely low and very unlikely. Symptoms are not used for diagnosis of HIV so continuing to discuss how many bumps you have isn't productive.
