Don't think so, if the pains start again a would phone the mw to be checked out as my last two labours started with period pains, my last baby was born at 32 weeks and came out of hospital 10 days later healthy
i'm 5ft 9 and my first went into labour with my first at 36 weeks (he was born 36weeks and 6 days) so i don't height makes a difference, i didn't have any signs he was going to be early other than a show and 2 days later i had my baby, it's not something you can predict, i'm 38 weeks and 3 days with my second now, had a show last tuesday and still no baby, i think its the luck of the draw lol
I am 4"11 and size 6/8 pre pregnancy and currently 9 days overdue! I was convinced I would go early for some reason but here I am.... going in to hopsital tomorrow to be induced. I was the same I had everyone telling me I would go early. Had really easy pregnancy with no symptoms/problems so been really lucky. Head still not engaged though, at the moment they don't know if baby just going to be one of those babies that doesn't move down until labour or if pelvis too small. Will soon find out I guess!! I have been assured that our bodies don't make babies that are physically too big for us to deliver!! I certainly hope this is correct as I only have tiny baby sleepsuits in my hospital bag
Anyway what I am trying to say is I don't think being small means you will go into labour any earlier than normal. If you are feeling back to normal and no other sickness/pain then try and relax. Good luck!
