Hi Sherif and welcome
That is a low reading part way through treatment- I did 24 weeks, I wasn't undetected until 18 weeks on treatment, I still cleared, it is not at all unusual to get your result of . Looks to me, patient not doctor, like you are on track really well.
Taking your meds with some food? Keeping hydrated and feeling ok?
