bicornuate uterus and worried about early labour

[Creolie]

Hi there, i have a bicornuate uterus and now im 35 weeks, i am convinced that my baby girl is going to be here in the next 2 weeks. i dont know i just have a feeling. What are the first signs of labour, i mean i know all the main ones but anything else? Like to find out your pregnant there are HEAPS of symptoms are there any other signs for labour? Like my belly keeps on getting REALLY tight and staying like that for ages, has been doing that for the last week
