Symptoms of going into labor as a first-time Mommy

As a first-time mom I'm curious of what your symptoms were 2 weeks prior to going into labor. What week did you go into labor when did you lose your mucus plug what pains are normal in third trimester I think I've been having a lot of Braxton Hicks sometimes I do feel pressure and pain like I felt pressure near my vagina and I had left side cramping at the same time while I was laying down it also happens another position also had an increased vaginal discharge
