FTM at 34weeks. When do you guys felt first sign of labour?

Hello everyone. I’m a FTM at 34weeks now. Today I felt a downwards pressure in my tummy and very very mild pain once in awhile. I have rather high tolerance for pain therefore I can’t tell if it is signs of labour. Does anyone one of you felt similar symptoms? At how many weeks do you guys start having signs of labour before your baby arrives ?? Feeling a little confused right now. #firsttimemom #advicepls #firstbaby
