BH or slow start to labor?

Ma

So ever since last night I have had “wave type” contractions- starting in my lower back, then moving to my whole uterus my lower abdomen. Last night I didn’t time them, but they felt pretty spread out, 15-25 minutes apart. Now today during the day, I’ve been feeling at least 3-5 “waves” of this feeling in an hour time span. Side note too—I lost a lot of clear/white discharge this weekend and even this morning saw clumps of it in the toilet. No bloody show, but more discharge than usual. Just curious to if anyone experienced a similar situation that lead to labor hours-a day later or am i just psyching myself out?!🙃😅 (38+4)
