positive test 5 days before missed period

i dont usually post but im feeling alot of thoughts its driving me crazy this morning i woke up and randomly decided to test due to synptoms i have been feeling the past week first test was the digital clear blue(fmu) and i feared it to be a faulty test maybe false positive which ive read alot about those test so i waited another two hours and took a first response which had also come up positive, then an hour later took a strip test i had got off amazon also faint positive then continued testing today because of the shock i was in , my fear is that something may go wrong from testing so early , anyone else go through this or have any thoughts?
