Pains down below

I am 35 weeks plus 2 days with my first baby and was woken up in the middle of the night with what I am putting down to braxton hicks, although these were more regular and in my back as well, this went on for about 2 hours and finally stopped. When I woke in the morning my bump ached all over, it felt as though i had done a thousand situps, my next antenatle appointment isnt for another week. Any ideas of what happened to me?
