Need advise, is it herx or not?

Hello, I started 2 weeks ago a herbs protocol from a pharmaceutical in Australia, that has good results for Herpes virus, which among others I have (also CMV, Epstein bar). I started slowly one capsule, then other, because I am very sensitive, to see if there where any side effects. It has astragalus, rhodiola, lysine, tribulus and other, not especific. I was able to take all 5 for 4 days, everything was well, I even had a great day, before I started feeling sick. Now for the last 11 days, I have been feeling very sick one day and better (able to function), not well the next day....I even stopped all 5 herbs and then took only the astragalus the following 2 days, yesterday I did not take it and today again took it, because its good for the imune system and to fight viruses. This capsules don’t have any inactive ingredients shown on the package.
I know with the Lyme (mainly Mycoplasma) and my viruses I feel sick often, it is different, is 2 or 3 days feeling very bad (foggy, no stamina, fatigue) and then I get better; but this time it has been different, I have not been able to have a good day in almost 2 weeks.
I have had a lot of stress this weeks, but is not much different that many periods during this pandemia. I want/need to feel better, have things on hold, that I need to finish, etc....
Does anyone has experience similar symptoms with this herbs, do you think is a herx that is taking longer....
I do foot baths, drinks lot of liquids, Vitamin D, C.
Thank you for any advice
