Did anyone...?

Did anyone who has been taking Evening Primrose Oil start losing pieces of their mucus plug a few days after starting them? Last night was my 3rd night inserting them (2 every night) & I woke up to a chunk of my mucus plug coming out & some period-like cramps in my lower back & lower stomach. Im 37 weeks & 3 days. Induction is 11 days away. On the 18th.

Update:

I lost more of my plug this morning at 37 weeks & 4 days.
