advice needed no silly answers please?

had sex twice on two different occasions both were protected with a condom. which never broke. as extra precaution I took the morning after pill twice in the same month the first one I took 10th june and had a period 17th june which was my normal time the next pill I took was 27th june so I am awaiting my period to come. I also tested for std which was 25th june which was 2 weeks after the first sex which was negative and now have done another std screening on Friday just gone with gp she said when these results come back that's it no more test needed. of course the last sex was seven days prior to the gp tests.

my questions?

would the first std result be accurate for the first sex?

would the second set of std testing give an accurate result? gp said it would as its 7 days after sex so enough time?

also could the morning after pill be causing my bladder to have pressure as of the burst of hormones as it suddenly did happen after I took the second morning after pill?
