Signs?!

Samantha • Proud wife 💍 Teacher 🍎 Baby #1 on the way 🤰🤱

Im currently 37+6 with my first baby! For the last three hours I’ve been super nauseous, can’t seem to get off the toilet, and on and off light cramping. Also a constant stomach ache and head ache. Could this be a sign that labor is near ?
