So this is my third pregnancy and i am currently 39+1

I have had two straight forward vaginal births and plan to have a home water birth this time around. For some reason this time though every time i get a few twinges or any sort of labour like symptom i start to feel really nervous and panicky, i dont know why and i want to try and stay calm. I know i can do it coz ive done it twice before, naturally aswell so i dont know why i feel this way! Anyone else feeling the same?!
