May have made a minor mistake on my UCAS application. Panic?

When I was doing my application, I used an old planner from my GCSE time as it was the first thing I found. My teachers had all told us to write down the dates of the exams in our planners when they found out and told us, but I never really used that as shortly afterwards we got a proper timetable.

Fast forward to now, I've received offers from all of the universities I applied to as of this morning and have just by chance stumbled across my GCSE certificates. Looking at them, I'm worried I may have put more down as June than were actually taken in June. I remember the majority being put as June on the application, but I'm worried now there may have been a few in either May or July which I put down as June. I'm hunting for my planner now to find out if any of the dates in it were in fact wrong, but I'm freaking out. Will universities care about this, would they withdraw the offer because of this? If it turns out a few are wrong, should I contact UCAS and try to get it fixed, or leave it? I don't want my offers taken away because I may have sat English in May and not June!
