Good evening everyone?

Good evening everyone ? Today at lunch I felt real contractions and realized what it means to have "pulling in my belly" and what real contractions feel like - pain in my lower back and abdomen, 39.4 weeks ? Still having brown spotting on my daily pads, attaching photo and sorry in advance ????? How soon can the birth happen? And who had this experience?) My doctor was, sent me home and said wait)
