Those of you who have had preterm labor

Tera

What signs did you have leading up to delivery? I’m 35+3 and all day yesterday I had period like cramps then even was woken up from them at 2 am, had to take Tylenol to get them to go away. I also feel intense pelvic pressure like she could fall out at any moment. Moving around is so uncomfortable. Never experienced anything like that with my first!
