Would you consider
Your stomach being super tight and not easing up much but no pain a contraction? I was induced last time and I don’t know if it’s baby time or not. I was also vomiting all day yesterday and in the bathroom today. My stomach is so tight it’s uncomfortable to sit up or even stand.
That's how mine started. Just ride it out and see if it gets worse, if it starts getting worse, consistent, or painful then start timing them. I didn't have real pain until I went to the hospital though and I was a 7 when I got there.
In the meantime I'd go take a shower, drink some water and have a snack. You'll know if it's go time.
That's how mine started. I went to try to nap and couldn't sleep with the tightness, and then noticeable contractions started a few hours later.
