That sounds like when I went into labor with my son. I felt very constipated, alot of pressure.
You will definitely know 😂 I’d get on an exercise ball and keep engaging baby, do some walks, stay relaxed baths or a hot shower! Watch something funny or listen to music to get the feel good hormones going. I’d look out for any signs of discharge I was a week over due when LO came! The day of I had my bloody show and lost my mucus plug, baby came 12 hours later! Good luck 😊
All I can say is you'll know when it's a real contraction🤣 it will take your breath away and very painful. Mine started off like period pains but very very intense
