Almost 37 weeks and so many bh contractions

KP • Mama of two DD 04/14 and DS 03/16. #3 and last due 3/19
Maybe because it's #2 for me and it's more common than ftm but I get bh contractions all day long. Sometimes they have a little bit of pain but mostly lots of uncomfortable stretching. At 36w1d I was 1 cm dilated with high cervix. I'll be 37w on sunday. I was 5 days early with dd, assume I will be early again. Any other stm experiencing a LOT of bh all day?
