is this something to worry bout

Last night I had 14 BH contractions in 20 min. I had a little bit of clear discharge but when I stood up an moved up a bit they went away. As soon as I sat back down they started up again and they were more cramps than just the tightening they were yesterday. Haven't had anymore an just woke up with a headache an nothing else. Call my doc? Go to l&d? Or not worry bout this? I have been to l&d twice this pregnancy for kidney stones and pancreatitis an I just feel like I'm being stupid this is my third baby and I should know better being a nurse but I haven't been pregnant in 6 years and I never had this before. TIA! ❤ btw 33 weeks and 1 day.
