I honestly give up on timing contractions

I am not good at it. All I know is last night I didn’t sleep at all. I’m 40 weeks and 3 days. My stomach kept getting so rock hard last night and I would feel such heaviness on my pelvis along with period cramps. I wake up this morning and it feels like the baby’s halfway in my vagina and my stomach keeps getting rock hard. What’s going on here 🤯
