What does heavy period like cramping mean towards the end of pregnancy?

37 today and I did not sleep I’ve been cramping on and off all day then specifically at night when I went to bed it just got worse. The last 3 nights it woke me up. But last night it kept going & coming. I called the nurse yesteday bc I had some faint blood in the morning & she said it’s my cervix opening up but the cramps just got worse when I left work. Not sure if I should be calling them again today if it keeps happening or if it’s normal is this a sign for early labour ?? I’m not due until August 24th and I don’t see my ob again until the 7th
