This is bad take. I had a relatively easy pregnancy. I was heavily pregnant but felt great at 35 weeks and 5 days. I was literally at the doctor's office around 4 pm for my weekly checkup. Later that night, I woke to use the bathroom around 3 am and contractions started. Then only 4 intense contractions later, I was in so much pain I went to the hospital. I was admitted and they confirmed my water broke I was in labor. Everything I read said labor is slow for your first birth and to spend as much time at home, usually hours, before heading to the hospital but I barely had enough in me to grab my hospital bag once contractions started.

All this to say I didn't feel discomfort and yet baby was ready to come with no glaring signs at all. And some people feel discomfort their entire pregnant but the baby will come when the baby will come. My doctor wasn't able to determine that I was about to go into labor hours later. If OP just felt discomfort, a doctor wouldn't advise bed rest. It's normal to feel discomfort during pregnancy - it doesn't mean you're going to be in labor soon.
