early labor signs or still have some time?

i’m 37+4 and last night my back and ribs started getting some serious pains and my calves started killing me with swelling in pain but i really had a normal day taking it as easy as i can with two toddlers. by 10 pm i got super nauseous out of nowhere and threw up. this morning my calves and ribs feel bruised and im still pretty nauseous and now lightheaded, having some serious pelvic pains. i thought baby had dropped around 35 weeks but yesterday my belly just got super low, to the point that its sloped off and it looks even more so today. i’ve had a couple painful contractions throughout the night and this morning but nothing consistent yet. i lost my mucus plug with a pink tinge on halloween. does this sound like early signs of labor to anyone? i know it could still be days but i told my fiancé weeks ago i thought she would come today, on this rainy day, just on a whim and it would blow my mind if i was somehow right lol. my 4 year old said she’s coming Sunday (pic of my belly posted after this post, cant get a picture to attach to this post or in the comments)
