What early signs of labor did y’all experience in the days/week leading up to having your baby? When did you lose your mucus plug?

My son was measuring almost 7lbs at the 36 week growth ultrasound and I’m worried that he will be too big if I don’t go into labor soon lol. I’m almost 39 weeks so I can only imagine he’s close to 8 or 9 lbs already!

Did y’all do stuff to self induce before you went into labor? Did anything noticeably work? Feel free to share your experiences as I’m a first time mom and would like any bit of into I can get! Thanks❤️
