Labor question

When I got pregnant before testing (got my first positive at 8 dpo) I just knew I was pregnant. Then I just knew it was a boy and it is. I'm 37 weeks today and the past few days I've been SO energetic and nesting of course haha well today still lots of energy and I've had contractions since for 3 hours 15 minutes apart lasting 50 seconds (they are basically exact in time). I can feel him in my pelvis today much lower than yesterday. I feel like I'm going into labor, slowly like with my daughter.
